Information as to the strengths of War Office headquarters branches in August, 1939, is not readily available. The total strength, military and civilian, in April, 1939, was approximately 3,700. The corresponding figure at 1st October, 1947, was 10,600. In April, 1939, 13 buildings and blocks of houses other than the main War Office building were occupied. At the present time 28 such buildings and blocks of houses are occupied. I would point out, however, that this comparison is of little real value as the buildings concerned range from large blocks of offices to quite small houses.
