Books on Second World War supply convoys

Which books best cover supply convoys in the Second World War?

The panel recommends Kenneth Poolman's armed-merchant-cruiser work and mentions Gorshkov's sea-power book, then shows a military transportation history whose title is unclear in the spoken exchange.

Kenneth Poolman's work on armed merchant cruisers is recommended, with a section on merchant aircraft carriers noted during the discussion. Gorshkov's sea-power work is also mentioned.
