SUMMARY OF OPERATIONS OF BOMBER COMMAND FOR FOUR . WEEKS ENDING 3RD DECEMBER, 1944.

MEMORANDUM BY THE SECRETARY OF STATE FOR AIR.

A.—A detailed summary of operations is appended. B.—Results of Operations. 1. Tirpitz. THE Battleship Tirpitz was sunk on the 12th November in an attack made by 29 Lancasters, each carrying a 12,000-lb. bomb. Three direct hits were obtained, one of which hit the ship near the bridge and penetrated and split open her port side, while other bombs fell across the ship causing her to capsize very rapidly (see Print No. 1).

2. Oil Targets. Attacks were made during the period on the oil plants at Wanne-Eickel, Homberg (Meerbeck), Castrop Rauxel, - Harburg, Sterkrade (Holten), Nordstern and . These attacks were all successful and the plants were temporarily put out of action, with the result that during the last week of the period the list of targets suspended from attack included all ten synthetic plants in the Ruhr and the refineries at Harburg. Print No. 2 shows the heavy destruction caused in thejplant at Welheim in the series of attacks made by Bomber Command and VIII U.S.A.A.F. Photographs now show that the attack made through 10/10th cloud by means of the G.H. navigational aid on the oil plant at Wesseling on the 30th October caused very heavy damage to the main installations, the gas-generating plant, the boiler-house, oil storage and offices. 3. German Towns. A number of attacks was made on German towns, but operations generally were limited owing to bad weather. The town centre of was virtually destroyed in a raid on the 6th November and many important buildings were heavily damaged, including a chemical works, a steel works and a cable works. On the same night was very successfully attacked, the greater part of the built-up area, including the main passenger station, being gutted or destroyed. The damage spreads northwards across the River into Koblenz-Lutzel, which suffered heavily, and also to a lesser extent across the River into Ehrenbreitstein. At the request of the Armies the fortified areas of Duren, Julich and Heinsberg were very heavily attacked on the 16th November. Almost the entire built-up area of Duren was destroyed with the exception of a small area due west of the marshalling yard (see Print No. 3). At Julich, the destruction was on an even greater scale and, as Print No. 4 shows, the entire built-up area was destroyed. Other towns attacked during the period include Freiburg, , , Miinster and . [28842] 4. Transportation Targets. Two attacks were made on the Dortmund-Ems which had been repaired since the previous' attack made in September. On the 4th/5th November the main (western) arm of the canal was breached and the eastern by-pass arm was heavily hit where it crosses the River Glane (see Print No. 5). As a result of the attack both arms of the canal were impassable and the water drained into the surrounding countryside. The second attack, carried out on the 21st/22nd November, was made at the point where the western arm crosses the River Glane. The aqueduct was wrecked, the western arm was breached and wide areas of the countryside were flooded. Print No. 6 shows the extreme accuracy of the attack. The Mittelland Canal, which lies to the east of and carries traffic between central and western-, was attacked on the same night. The western embankment at Gravenhorst was breached over a distance of about 50 feet (see Print No. 7) and about 31 miles of the canal is without water. Marshalling yards at Fulda, (Kalk) and Aschaffenburg were heavily attacked.

5. Results of Previous A ttacks. The attack made on on the 4th/5th November caused very heavy damage to both industrial and residential property. Amongst the many industrial plants severely damaged are the Vereinigte Stahlwerke A.G. and a factory making milling and grinding machines. In the raid on Knapsack on the 28th October heavy damage was done to the Goldenburg Thermal power station, the largest power plant in Germany. Photographs show that the turbine house, boiler and switch houses were all affected and the power stations rendered inactive. Print No. 8 shows the results of the attack made on Diisseldorf on the 2nd/3rd November, when all the factories in the north and north-east were severely damaged and the northern suburbs virtually destroyed.
