British logistics in the Western Allied invasion of Germany was the support of Field Marshal Sir Bernard Montgomery's Anglo-Canadian 21st Army Group's operations in the Second World War from 8 January 1945 until the end of the war in Europe on 8 May 1945. To conserve scarce manpower, the British and Canadian forces employed mechanisation and materiel to maximum effect. Prodigious use of ammunition, fuel and equipment demanded a first-class military logistics system, and by 1945 the British Army was highly experienced, professional and proficient.
