Destroyer Procedure

Destroyer Procedure was issued by Second Fleet as Ultra secret Standing Order #21 on !8 December 1943. It is 85 pages and like its companion document has numerous diagrams: Anti submarine search methods (4), echo ranging sweep formations (2), echo ranging by "bounds" (4), minesweeping (17), minesweeping for an anchorage (2), line abreast formations and regulations for maneuvers (1), evasive maneuvers when under aircraft attack (7), Special serpentine movements (4), 41 in all. The most interesting items are those special maneuvers for ships under attack. This sheds light on the notion that their ships maneuvered at random when under attack from the air. They did not.
