Here we can see the destroyed roof of the“Haus der Schweiz” and adjacent building at Unter den Linden 22/23 Ecke Friedrichstraße 155 on these two images taken from a video film. This original film-footage filmed on 10 April 1941 recorded the damage taken from the previous night raid by British RAF bombers over Berlin-Mitte, the one which destroyed the Opera building and several others too at Unter den Linden.
The Swiss House or ‘Schweizerhaus’ would be partly destroyed in 1945 the final Soviet assault to capture the city. Postwar, the DDR government reconstructed the building from 1950 but did not want to mess with Swiss banks. Nevertheless, they used the house for their own purposes.
[Still from film taken from a Russian newsreel following the end of the battle, May 1945. Soviet troops and vehicles (notice the American Jeep) at the ruined Friedrichstraße near Unter den Linden, the Haus der Schweiz can be seen at right.]
[The Friedrichstraße/ Unter den Linden corner in the East Berlin sector in October 1946. Notice splinter damage to the walls and columns of the building.]
The junction of these two main streets was heavily rebuilt during the post-war years as we can see in this picture taken in September 1959. The Café Viktoria was demolished and the space left empty during many many years as was the case in several other locations in East Berlin. Note Bhf-Friedrichtraße’sbridge in the background.
The world as we know, as historian Eric Hosbawms says, started that day. No other city was in the middle of the Twentieth century than Berlin. The Kaiser has abdicated, the Weimar Republic
started, the Spartacus Revolution triumphed… and Hitler and Hess waited for their time…
On 11 November 1918, Marshal Foch, as Supreme Commander, signed the armistice with Germany in the then-called “Wagon of Compiègne”. This agreement ended fighting in the First World War.
22 years later, in May 1940, Hitler forced the defeated France, the real enemy, to sign her surrender in that same car at the exact spot where it happened, Compiegne. Adolf’s revenge for the shame of 1918 was complete.
Then he took the saloon car to Berlin, exposing it as a trophy at Lustgarten in front of the Dom, so that all Berliners could admire it as we seen in these photos during the Wehrmacht Day´s celebration on 23 March 1941. Notice in the second image at right the Löwenkämpfer statue (´The Lion fighter`) besides main entrance of the Altes Museum.
73 years later, a Soviet Il-2 Shturmovik flies again over Germany during ILA (Internationale Luft- und Raumfahrtausstellung) April 2018 Berlin air show at Schonefeld airport.
One of the outright show stars of this year event was the beautiful Ilyushin Il-2 from the Wings of Victory Foundation based in Russia.
This restoration is from an aircraft recovered in 2011 from the bottom of a frozen lake.
[A squadron of Il-2s from 16th Soviet Air Army flies in close formation over Berlin in May 1945.]
The IL-2 was a ground-attack plane from 1941, designed by Sergei Ilyushin, it was very feared by German troops on the ground, who dubbed her“Der Schwarze Tod”(The black death).
It was an outstanding design thanks to its endurance, fire-power and heavy armor. With 36,183 units produced during the war, it was the single most produced military aircraft design in aviation history.
During the final Battle of Berlin in April 1945, Shturmoviks bombed and strafed the city and their defenders to aid the Soviet troops to conquer the Reich’s capital.
[Several Soviet Shturmoviks parked on the grass between Luftwaffe aircraft wreckage at Tempelhof Flughafen Berlin in May 1945. This airport was captured by the Russians on 26 April 1945.]
In the last years Berlin city has undergone a radical transformation, with an influx of money from public institutions and private companies, far away from the cold days of the German reunification in 1990. This has benefited in the architectural modernization and services improvement for its inhabitants but in contrast led to the loss of its unique condition among other European capital cities: historical buildings, bridges, roads and streets, survivors of the 1939-1945 war years and its battle fires are all being refurbished to clean and nearly new condition (the Reinhardtstraße bridge of the Stadtbahn is one of the last examples of this).
Berlin is now losing its value as a “time capsule” from the past.
This battle-scarred building is located at Am Kupfergraben Ecke Dorotheenstraße nr 1 in Berlin-Mitte district, today home of the Humboldt-Universität zu Berlin School of Business and Economics.
With its walls full of signs of war, smoke and fire from Luftangriffe by British RAF and American air-raids, and shrapnel from howitzers and splinters due to street-fighting with the Soviets during the final Battle of Berlin in May 1945, it is an evident survivor of the destruction experienced by the city.
[Two pictures of this building before the restoration work, as viewed in 2008.]
The heavily damaged building was restored and cleaned a few years ago, helping in preserve it but in the process erasing forever its original state, much more blackened and holed, a true-live survivor of the aerial bombings and battles suffered by the city during the Second World War which now has lost its past.
[This aerial view taken a few days after the war’s end in Berlin, clearly shows the devastation suffered by Mitte district. Museumsinsel with Altes Museum is in the foreground, Unter den Linden crossing from top to bottom, and other main sites like the Zeughaus, Staatsoper, Humboldt Universität, and the green Tiergarten park far behind. Our “time-capsule” building is seen at extreme right, marked with a red arrow.]
It has survived in those conditions due to its location in Berlin Mitte, near the Museumsinsel. During the postwar years, located at the Soviet Occupation sector, it was repaired by a number of securing provisions of concrete and brickwork, a patchwork which made extend its life until the end of the Cold War in 1990.
[Different views of today’s condition of the Humboldt building.]
This building was built in 1879-83 with a four-storey sandstone facade in Italian Renaissance forms mixed with simple Prussian functional design.
It was renovated in 2002 to be the Faculty of Economic Sciences and from 2009 started the restoration of the roof and facade in cooperation with the Landesamt für Denkmalpflege (the State Office for preservation of historic monuments), with emphasis in that the signs of war remain legible on its 1.200 m2 facade.
The work was made by Ellwart Steinrestaurieung, an experienced company focused on monument and ancient buildings restoration, in close cooperation with the architecture office Martin Focks. In their study they asked themselves before the restoration began: “…Can a façade repair appropriate to the monument be realized without neglecting the age value of the building and without distorting or even eliminating the historical traces of war damage?”
Massive work was made to exchange the facade stones as well as a removal of post-war provisories, but not the projectile impacts. The final result is a mixture of two periods, with a facade full of holes in a secured and cleaned building.
It costs approx. €2.5 million and ended in the Autumn of 2013.
[Close view of one of the several graffities which ‘adorn’ the building before the 2009-restoration project.]
[And compare it with a 2013-year view…Notice at upper right that the missing stone cornice of the facade seen in previous image has been retrofitted during the restoration project, and the overall condition is more clean.]

This week we celebrate the 70th anniversary of the start of the “Berlin Luftbrücke”. When the Soviets blockade Berlin on the night of 24 June 1948, the only way to supply the city from West Germany was by plane.
US President Truman and the National Security Council (NSC) formally stated America’s determination to remain in Berlin. They named it “Operation Vittles”, and began on 26 June with the landing of a Douglas C-47 Skytrain in Tempelhof.
American and British airmen made a risky non-stop work flying across Soviet East Germany in unarmed airplanes, and there was also a large supply of ex-Luftwaffe airplane mechanics available right in Berlin. Pilots from Australia, Canada, New Zealand and South Africa also joined the ranks.
The Allies used hundreds of transport and cargo airplanes from RAFTransport Command and the USMilitary Air Transport Service, and even private operators aid on the effort with their aircraft and cargo trucks. They included civilians as well as military personnel. Some facilities and airfields were improved to accomplish the operation, the old Berlin Tempelhof too, with the construction of a new runway and landing strip to the south of the airfield. A long distance radar was installed on the main building of the airport to guide the aircrews to West Berlin. Even a new air base was built, airport Tegel, with the French authorities ordering the construction of a 2428 m (7,966 ft) long runway, as Tempelhof was not big enough to accommodate all relief aircraft.
[Berlin’s Neukölln children watching from a pile of rubble an American transport Douglas C-54 in her final approach to landing at Flughafen Tempelhof.]
Why is the Berlin Airlift related to the bombing of the city during the war? The same young men that 3 years before flew through Flak and enemy fighters every day and night to bomb the Third Reich’s capital now make the same trip but to carry milk, coal and food to the blocked city. Many former US bomber pilots volunteered for duty in the Air transport command in the new born-USAF. This is how former enemies became friends in the Cold War.
[Here, three US airmen check the cargo load inside a C-47 Skytrain during the Berlin Airlift. Notice they even wear their WW2-era flying jackets, the patch on the shoulder on the men at extreme right identifies him as a China-Burma-India veteran.]

Notice that the last meters of the landing pattern were overflying several cemeteries at Leinestraße in Neukölln.]

This photo was taken at Gatow airfield, on 19 August 1948. Note that some of the kids are barefoot, a post-war common sight in the defeated Germany.]
At the end, with almost 278,000 flights, more than 2.3 million tons of freight was transported, feeding 2 million people by air with 1500 flights landed in Berlin every day with enough cargo to supply the city indefinitely.
31 US airmen and 40 British lost their lives during the Berlin airlift, and on 20 July 1949 the US Congress awarded the Medal for Humane Action to members of the US Army, Air Force, and Navy who served in support for at least 120 days during the period 26 June 1949 through 30 September 1949. Lest we forget.

[Armourers from No 97 Squadron preparing MC-bombs on their trolleys to be loaded onto a Lancaster bomber on July 1943 at RAF Waddington.]
The limited and inadequate arsenal of bombs composed of the high explosive GP (general purpose) bombs (10-15% detonation failure rate) made British Bomber Command to develop a new range of explosives: these weapons were the Medium Capacity (MC) Bombs, which had improved metal to explosive ratios and also proved more reliability and generally exploded on impact, unless fitted with delayed action fuses. Basically, higher explosive into lighter cases to obtain a greater blast.
The analysis of the destruction inflicted by Luftwaffe’s bombers over Britain, particularly by the Germans’ SC (Spreng Cylindrische) series of bombs (usually filled with a mixture of 40% amatol and 60% TNT), with their higher charge to weight ratios and destructive power, marked the new requirement.
[This is a German SC 2500 ‘Max’ bomb (5,000-lb/2,300 kg), the biggest one of this series, ready to be loaded in a Heinkel He 111H-5 medium bomber at a Luftwaffe airfield during the final phase of the Battle of Britain in 1940. Due to its massive size, this weapon had to be carried externally attached to a reinforced ETC2000 bomb rack.]
The first bombs dropped on an air raid were high explosive bombs, to shook the people and lead the way to the incendiaries, the actual fuse of the destruction into the streets. Vast swaths of fire engulfed the town, and then the RAF attacked again with their MC-bombs, a last punch of destruction to spread fire and keep firefighters away and to avoid wardens and police officers to drawn out and assist the city and their people. The roads and streets, and water pumps were destroyed and harassed by craters and blows, incapacitating the workforce.
[This crater was made by an explosive bomb dropped by Bomber Command into downtown Berlin in October 1940.]
The 500-lbs MC (227 kg) bomb was first introduced in to the Command’s inventory at the end of 1941, the bomb contained twice as much explosive of Amatol than its GP equivalent and became a mainstay for bombing operations due to its much greater blast effect. As the war progressed, the Air Ministry scientific advisors and experiments made by Solly Zuckerman (a scientific advisor to the Allies on bombing strategy) found that blast effect rather than penetrative power was more important in destroying buildings.
[Men from No 77 Squadron, based at RAF Elvington look on as the message ‘we hope this hurts’ is chalked onto a 500-lb MC bomb prior to their fourth attack, on Berlin on 30 January 1944.]
However, they still lacked aluminized explosive like German bombs, which would have rise the effect more than three times. By March 1943, 19 firms were producing bomb bodies nearly at 18,000 a month and the MC bombs formed the main bulk of destruction tonnage dropped by Bomber Command on Germany, with the heavy 1,000-lb version being introduced in the spring of 1943 as a very effective weapon and about a quarter of a million were produced by the end of the war. It became the standard British bomb.
[Armourers prepare to load 500-lb MC bombs into De Havilland Mosquito B IV, DZ483 ‘GB-R’, of No 105 Squadron RAF at Marham, Norfolk, in preparation for a night raid on Berlin by aircraft of No 2 Group in 1942-43. At this time, Mosquitoes, flying alone in the dark, usually carried a bomb load consisted of four 500 MC, an explosive ‘present’ sent just to disrupt and keep the head of the enemy down.]
[British ‘1000-pounders’, MC bombs, await in their trolleys to be loaded into this No 76 Squadron Rolls Royce Merlin-engined Halifax heavy bomber, W7805/’MP-M’, being bombed-up at Linton-on-Ouse, Yorkshire on 3 April 1943. This bomber failed to return to England that night, during the bombing of Essen, one of the 24 aircraft lost. W7805 was probably hit by Flak, four men of her crew perished on the crash.]
[..and the sight after being loaded in the bomb-bay. Here, we can see the usual load for industrial demolition, factories, railyards, dockyards (know as ‘Abnormal’), loaded in the bomb-bay of an Avro Lancaster of No 9 Squadron RAF at Bardney, Lincolnshire, before a night raid on Stettin. ‘Abnormal’ consisted of 14 x 1,000-lb MC high-explosive bombs. When RAFBomber Command bombed Berlin the target wasn’t her factories, the aim was to destroy the city and the people’s morale, so only a few part of the attacking force carried this type of load during those raids, mainly some of the Pathfinders and the last squadrons to be scheduled over the target, with a mix of instantaneous (nose-armed) and long-delay (tail-armed) fusing-bombs.]
The explosive bombs shook everything around and fill the target with destruction, noise and dust into the streets. It is estimated that during the attacks on the Hauptstadt during the Winter 1943-44 by British Bomber Command, 9,390 Berliners civilians were killed. The city resisted and their defences inflicted a severe blow to the enemy campaign, but moral fell to a minimum.
[A shocked but alive family is helped by a young member of the Luftwaffe through the rubble on a street in Berlin from a demolished building, following Allied air raids during 1944.]
During the war 758,408 tons of high explosive were despatched on Bomber Command aircraft, and would drop some 253,800 1,000-lb MC bombs along with 403,000 500-pounders.
The research done by the USSBS (The United States Strategic Bombing Survey) and John Fahey’s paper indicate that on average, it cost the British Government £1.00 per 23.4-lb of HE bomb weight purchased. At this price, the total value of high explosive bombs despatched to targets by Bomber Command during the strategic air offensive was £72,599,749, but it is important to indicate that these figures were just the guesses of economic experts, due to the impossibility of getting reliable information.

This is a British 1000-pounder (500 kg) MC bomb from 1944 today at Berlin Mitte. Thousands of people around Berlin’s Hauptbahnhof (the main railway station in the city) were evacuated last week to allow disposal experts to defuse an unexploded World War II explosive dropped by Bomber Command and unearthed on a building site. It is one of the 253,800 bombs of this type dropped by RAF bombers during 1939-45 in all war fronts.
In 2011 it was estimated that over 5,500 unexploded bombs or weapons from the war that need to be defused are uncovered each year. The daily average is 15, most of them aerial bombs.

Incendiaries (IB), usually small-sized weapons, were carried in an aircraft bomb-bay using Small Bomb Containers (SBCs) and were packed into clusters. The device was not aim able and once dropped often became effected by cross winds. This resulted in incendiary attacks become wide spread downwind of the target and also lead to other bombers being struck by falling bombs. Incendiary bombs function on impact. The heavy reliance of Bomber Command on highly inaccurate incendiaries shows that fire-raising was a major weapon in the strategic air offensive.

The mainstay of the Command’s incendiary devices was the 4-lb Magnesium (IB) bomb. RAFBomber Command dropped 80 million of these small incendiary bombs during World War II. In May 1943 efforts were made to developed a delivery device for the ‘four pounder’IB which would allow for them to be aimed and therefore more accurate during the raids.
[A member of the Luftschutz, Reich Office for Air Protection holds a stick-type incendiary bomb dropped by British bombers during a night raid in Berlin, March 1941. It seems to be a red nose colored 4-lb (1.8 kg) incendiary bomb made from magnesium and thermite.]
[A British 4-lb. Mk IV type incendiary bomb (“Brandbombe”). Top: complete device, nose is red colored. Middle: dud found without the tin plate tail, Bottom: the remains after burning. This bomb was made from magnesium in a hollow body made from aluminium with a cast iron/steel nose, and filled with thermite incendiary pellets. It was capable of burning for up to ten minutes. Its size was 54.35 cm long. This one was dropped over Würzburg in 1945.]
In April 1941, 12 millions incendiaries were ordered for the rest of the year and 36 millions for 1942, but because of magnesium shortages, production just reached ‘only’ 2.2 million in the ninth months of 1941, and 11.8 million in 1942, but these figures were more than enough for a force not yet converted fully to mass incendiary bombing. This very large numbers of production had enormous requirements on the Britain’s war effort.

Her deadly cargo consisted of 12 SBCs each loaded with incendiaries, in this case, 236 x 4-lb incendiary sticks. In the centre can be seen a 4,000 impact-fused HC bomb (‘Cookie’).]
[As war progressed, RAFBomber Command used several types of containers to drop Incendiary bombs. These are Cluster Projectile 500-lb No.14 Mk I falling on Germany. Two 500-lb incendiary
clusters plunge toward their target over Kiel. At left, one of the containers has broke and scattered the incendiaries like match sticks. The other big bomb has not yet broken but will do so momentarily. They were Dull red overall, one of the tensioning straps painted bright red and each one contained two fagots of 53 bombs each, a total of one hundred and six 4-lb incendiary bombs. Later, Cluster Projectile 500-lb No.17 Mk II tailed bombs and US-made cluster containers were used too.]
The other main type of incendiary-bomb dropped by Bomber Command was the 30-lb J-Type IB phosphorous. The Germans considered this a ‘morale weapon’ because it was impossible to extinguish with water due to its benzon-gel and was more stronger than 4-lb IB. Regardless of its short life span of this type of bomb on the war over 400,000 were dropped.

On this occasion, the incendiary bomb was used however as a precision target marker at night for the incoming main bomber force but shows to good effect how an IB explodes, Cheshire tried his low-level marking techniques on this raid, leading 12 Lancasters of the Squadron to the target.]
Handley Page Halifaxes usually carried the main bulk of incendiary bomb load on Bomber Command missions, so when they’re hold on reserve after high losses over Berlin in Fall 1943 the British offensive lost a high percent of fire destruction.
Breakdown, by type, of incendiary bombs dropped by RAFBomber Command during World War 2. Source: Burls, Nina. RAF bombs and bombing. ROYALAIRFORCEHISTORICALSOCIETY. Journal 45. 2009.
By 1944, the percent of total incendiary bomb load in a city attack by BC was around 70 percent and this support the claims made by Arthur Harris that the incendiary bomb was the most significant type of munition deployed by Bomber Command.
Of the total percent of bombs despatched by Bomber Command during the war 20.5 % (196,256 tons) were incendiary bombs. The economic cost to Britain of manufacturing incendiary bombs for BC was approximately £73 million, which means that those weapons cost slightly more than 50 percent of the total cost spent on bombs during the entire period of the campaign.

Fire, as Bomber Command well knew, was the biggest destroyer of property.
On 23 September 1941, Britain’s Air Staff produced a report detailing the effectiveness of German incendiary attacks on Britain and recommending that fire be a central feature of Bomber Command attacks. The key lesson to be learned from the 1940 German ‘Blitz’ (as it was to become known in Britain the air bombing campaign, 7 September 1940 - 11 May 1941) was that concentrated use of incendiary bombs was the most effective form of annihilation.
In 1941, approximately just 12 percent of the total bomb loads despatched consisted of incendiary bombs. The response was the ‘Incendiary Plan Unison’ ,issued on 25th October 1941 and first tested against the city of Lübeck on March 1942. That year the figure raised to a 42 percent of the bomb-load.
The RAF had to develop the required technique to burn out an entire city and the method was copied from the German raids and largely improved by British scientifics and physicists. The combined work of the Research and Experiments Department and the Air Warfare Analysis Section to estimate the nature of bomb damage and the vulnerability of German buildings made an essential contribution to what bombing could achieve. Led by Dr Reginald Strading, and with German-born Oxford physicist Frederick Lindemann among these top-men, this statistical research group produced from September 1940 accurate figures for air warfare operations from the damage done by Nazi bombs, and applied them into German cities in future attacks in terms of lives lost and houses destroyed.
New chemicals weapons and reactions had to be created to allow new Bomber Command fire-rising tactics and this let to a change in Britain’s industries and set as the most urgent problem to develop the technology to find an entire city at night and poor weather (mainly navigation aids).
[Death from above • A British RAF four-engined bomber -a Short Stirling, overflies the firestorm during the bomb run on a night mission against a German city.]
Germans had well knowledge about fire-bombs and their destruction capabilities, as they had employed them in large numbers against Britain during the ‘Blitz’ attacks in 1940-41, and although well prepared for a fire-air attack, the defences and fire-fighting equipment of Berlin and other main Reich cities were well overwhelmed by the massive size of the RAFBomber Command offensive.
In total around 110,000 tons of incendiary bombs were dropped during the ‘Blitz’ on England by Hitler’s Luftwaffe, twice the number of explosive weapons dropped. Fire was the biggest threat during the campaign and 95,000 Britons were drafted into the Auxiliary Fire Service.
[The ‘Blitz’: Buildings burning in Manchester after a German air raid on the night of 23 December 1940.]
Meanwhile, on Germany during inter-war years several drills were instructed as more evident became the idea that air power and air-raids against civil population and towns would be the main form of attack in the incoming war.

The main objective of the use of incendiary bombs in a carpet-bombing was to create a Firestorm. Fortunately for Berliners, the German capital was too big in size (the third largest city in the world) and was a more modern city than Hamburg or London, with more wider residential districts and there are more open spaces. Berlin blocks of flats were also of sounder construction. Even the powerful RAF Bomber Command was ineffective in burning out such a large city from end to end. Instead, smaller cities like Hamburg, Dresden or Hanover would suffer this aerial punishment of fire.
The success of the Hamburg raids (‘Operation Gomorrah’) in July 1943, a textbook example of the incendiary attack planning, confirmed the theory of the superiority of incendiary over high-explosive bombs and impressed the Americans.
[This is a vertical photograph taken from 19,000 feet during a night raid on Hanover, showing an Avro Lancaster, silhouetted by the many incendiary fires below. That night 3,932 buildings were totally destroyed, and more than 30,000 damaged in varying degree, by the intense conflagration in the central and south central districts of the city resulting from this attack.]

Detailed evidence from Britain “blitzed” cities suggested that incendiary bombs had five times the destructive potential of heavy explosive per ton. It was estimated that an initial salvo of 30,000 4-lb incendiaries had to be dropped in 20 minutes as a minimum to produce a firestorm. High explosive was needed only to reduce water supply and ventilate the attacked buildings.

When British Bomber Command went to war in 1939 it found itself equipped with a very limited and inadequate arsenal of bombs.
General Purpose GP Bombs:
The high explosive GP (general purpose) bombs, developed from 1935, were the initial arsenal Bomber Command had to carry destruction to Third Reich soil and people, but these had a ineffective performance and their explosive-to-weight ratio was low.
During the first three years of the war, RAF bombers usually flew with a small bomb cargo. In the case of Bomber Command attacking German industries and cities, the normal load were 500-lb (227 kg) and 250-lb GP (114 kg) bombs for hard targets and 40-lb bombs in containers for “soft”, plus the 20-lb (F) anti-personnel fragmentation bomb used mainly on tactical missions. For the 20-lb and 40-lb bombs, purpose-made packing pieces secured the individual bombs as a cluster within each partition. This early series of HE bombs used an explosive mix called ‘Amatol’, a mixture of TNT and ammonium nitrate.

inscription in Polish reads: ‘Warszawiacy Berlinowi - From Varsovians for Berlin’. 300 Sqn crews bombed Berlin for the first time during the mission made on 21 March 1941.]
The initial British trio of bombers -Wellington, Whitley and Hampden- were lumpered by their small capacity of the bomb-bays and by the fact of being twin-engined planes, the more ton of bombs loaded means less fuel capacity. Berlin was at 950 kilometres (590 miles) from London in the very extreme range of RAF ‘twins’. For example, the max bomb-load of a Vickers Wellington was 4,500 lb (2,041 kg) of bombs, but this figure was reduced to only the half when the type attacked Berlin to be able to reach it.
The size of bomb-bays in RAF aircraft and the perceived chance of a hit were both real considerations in this early period. During 1940, use of the smaller ordinance (over 2,000 20-lb F; over 26,000 40-lb GP; nearly 62,000 250-lb GP) far outstripped that of the 500-lb GP (just over 20,000).
[Armourers fit fuzes to 250-lb GP bombs on their trolleys, prior to loading into Handley Page Hampden Mark I, P1333EA-F, of No 49 Squadron RAF at Scampton, Lincolnshire. P1333 never
reached Berlin, being destroyed returning from a raid on Merseburg, Germany on 17 August 1940].
At the beginning of the war, HE (high explosive) bombs were considered the best weapon to use, with incendiaries employed in small numbers as a harassment measure; but the change in the bombing tactics from industrial targets to civilian and ‘area’ targets led the way to a mixed load comprising a much higher ratio of incendiary bomb to HE during the final years of the conflict.

In those early days of the conflict, RAF bombs were painted in a light tan colour, later orange yellow and finally dark green.
The 250-lb and 500-lb GP bombs were still extensively used in 1941, until the more capable high explosive bombs were developed and brought into use. All these bombs became available in quantities too large for the existing bomber force in use; the RAF had the bombs but not enough bombers to use them against the Reich. For example, in October 1941 there were unused stocks of 121,000 tons of bombs at Britain depots.
[Armourers wait for the conclusion of an engine test on Short Stirling Mark I, OJ-N, of No 149 Squadron RAF, parked at the end of the south-east runway at Mildenhall, Suffolk, before loading her with 250-lb GP bombs for a night raid on Essen, Germany. Each bomb has been fitted with a shackle to enable it to be winched into position in the Stirling’s high bomb-bay.]
[Bomb bursts straddle the machine workshops in the naval arsenal as another stick of 500-lb GP-bombs falls toward the target area during a daylight raid on shipping and installations by Venturas of No 21 Squadron RAFon Brest, France.]

The GP bombs had a high detonation-failure rate (10-15%) and the introduction of the heavy four-engined bombers such as the big Short Stirling just augmented the ton of explosives dropped on the Third Reich, not the effectiveness of the raids.
In conclusion, during 1940-41 RAFBomber Command was inadequate to destroy such a large city like Berlin was and tried to grow the number of raids against the capital, all of which did little damage. This gonna led to two vital changes: the development of the more potent MC and HC bombs, and the introduction from mid 1941 of the new heavy four-engined bomber force.
