By 1941 the Royal Navy could not concentrate every desirable ship in the Mediterranean because the Atlantic and other theaters still demanded protection. The forces available for Halberd were those that had survived Norway, Dunkirk, Crete, and repeated Atlantic and Mediterranean operations. Edinburgh's timely completion was fortunate, but replacements for losses could not appear quickly. Planning therefore had to account for the diminished force still operating six months into a war. Wartime attrition has direct implications for procurement, reserves, and a force structure that can continue operating after early losses.
