Wartime Britain was not literally isolated: Australia, Canada, India, New Zealand, other imperial forces, and European free forces all contributed. Much early-war escort crewing drew on existing reserves, separating personnel mobilisation from the problem of dockyard labour and supply chains. French yards were difficult to use as a replacement industrial base after France fell. Canadian production expanded quickly because Canada had the larger population and capacity, while Australian expansion took longer. These distinctions add institutional and industrial detail to the broader argument about Britain and imperial resources.
