25 March 1942
ATLANTIC OCEAN: The destroyer USS 'Blakely' (DD-150) is torpedoed by German submarine 'U-156' off Martinique, French West Indies. The explosion carries away 60 feet (18 meters) of her bow. Six men are killed and 21 wounded, but the ship makes it to Port de France, Martinique, for emergency repairs.
An unarmed U.S. freighter is torpedoed and shelled by German submarine 'U-103' about 75 miles WNW of Jamaica, and abandoned. 'U-103' surfaces and her commanding officer asks the Americans for the name and speed of their ship, and if all of her men have been accounted for, before he provides them with cigarettes. The freighter sinks early the following morning, after which time the U-boat departs.
German planes attack convoy PQ 16 as it proceeds toward Murmansk, USSR, from Reykjavik, Iceland; an armed U.S. freighter is damaged by near-misses and she leaves the convoy under tow of British trawler HMS 'Northern Spray'
GERMANY: During the night, RAF Bomber Command dispatches 254 aircraft, 192 Wellingtons, 26 Stirlings, 20 Manchesters, 9 Hampdens, 7 Lancasters, to attack Essen, the largest force sent to one target so far; 190 aircrew claim they hit the target many claiming hits on the Krupps works, but bombing photographs showed that much of the effort was drawn off by the decoy fire site at Rheinberg, 18 miles west of Essen. Essen's report says that only nine high-explosive bombs, 700 incendiaries and 1,627 leaflets were dropped there. One house was destroyed and two seriously damaged. Five people were killed and 11 injured. Nine aircraft, five Manchesters (out of the 20 dispatched), three Wellingtons, and a Hampden, are lost. Other targets bombed include Duisburg (by seven aircraft), Oberhausen (by two aircraft) while individual aircraft bomb Gladbeck and Hamborn.

During the day, nine RAF Bomber Command Bostons, with fighter escort, carry out accurate bombing at Le Trait shipyard. No Bostons are lost. During the night of the 25th/26th, 26 of 27 aircraft dispatched bomb the port area at St. Nazaire, 38 aircraft dispatched lay mines off Lorient, 30 aircraft drop leaflets over France, and one bomber hits Lannion Airfield.
