Nazi invasion maps of the USA. Plan Four is the much-discussed invasion by way of Gibraltar-Dakar-Natal-Trinidad, which President Roosevelt’s Good Neighbour policy has tried to defend against. It is based on combining the Japanese, German, Italian and Vichy navies, freed by the capture of Gibraltar and Suez. They must fight the Allied fleets somewhere. Invasion pours up the Mississippi Valley.
Axis Invasion – Plan Three calls for a southern Pacific crossing by Japan. Again the Jap Fleet, reinforced by the Germans, presumably has naval superiority over the U.S. Fleet. Probably first gun would be surprise bombing of Panama Canal, instantly followed by landings in Ecuador.
Nazi invasion maps of the USA. Plan Six is classic invasion down St. Lawrence and Hudson valleys. Germans could readily bomb Chicago, Detroit, Akron and rampage through Midwest. Big catch is getting past British Fleet. On all maps, black arrow alone means a feint; when combined with gray band, it means full invasion.
Axis Invasion – Plan Five is hard way to cross the Atlantic. Combined Axis navies reduce Atlantic islands, then take big water jumps from Azores to Bermuda to Norfolk. Their biggest headache is reported U.S. superiority in carriers. Twenty-five Nazi ships could transport four divisions.
