The Ministry of Ungentlemanly Warfare

In late 1941, at the height of World War II, the United Kingdom is struggling to halt Nazi Germany's attempts to take over Europe, with London regularly suffering bombing runs at the hands of the Luftwaffe. With their supply and aid ships constantly sunk by German submarines, Brigadier Colin Gubbins, with the indirect backing of Prime Minister Winston Churchill, prepares to initiate Operation Postmaster, an off the books black-ops sabotage mission intended to disrupt the Nazis' U-boat resupply operation on the Spanish-controlled island Fernando Po. While SOE agents Marjorie Stewart and Richard Heron depart by train, Gubbins enlists Gus March-Phillips to assemble a ground team to destroy the Italian supply ship Duchessa d'Aosta and two tugboats attached to it.
