British warships carried space for prize crews because capturing a merchantman created a double gain: the enemy lost a hull and Britain acquired one. The practice continued into World War II, when captured German and Italian merchant ships could enter British service and some provided conversion candidates for escort carriers. Even a large merchant fleet remained finite. Shipping assigned to India, Operation Torch, operations around Madagascar, and the Arctic convoys could not be used elsewhere at the same time. Merchant tonnage was an operational resource whose allocation shaped what an empire could supply and where it could fight.

Captured shipping and wartime transport capacity
British prize-taking turned enemy merchant losses into usable hulls, while World War II operations show how quickly competing demands could exhaust even a large merchant fleet.
