Conflict over Convoys examines the Battle of the Atlantic from the perspective of Anglo-American diplomacy, deepening our understanding of Allied grand strategy, British industrial policy, and operations TORCH and OVERLORD. Failure to build and maintain enough ships to feed the people and wage war made Britain dependent upon American-built merchant ships and American logistical support, yet British strategists aspired to dominate Allied strategy, while Roosevelt mismanaged merchant shipping allocations. The resulting gap between strategic ambition and logistical reality embittered the controversy over the 'Second Front'. Victory in the Atlantic finally led to American dominance of Allied logistics diplomacy and strategy. Conflict over Convoys relates these tensions to the decline of British hegemony and the rise of the USA to global influence.
