Note 1 — Chapter III · Plans Are Made and Forces Are Readied

American knowledge of the Japanese forces on Leyte was derived from many sources.1 The guerrillas on Leyte and other islands in the archipelago sent information to Australia on the movements, dispositions, fortifications, and defenses of the Japanese. Commander Parsons, on his submarine trips to the Islands, brought back with him important intelligence. Just before the invasion an intelligence officer from Sixth Army and one from the Seventh Fleet secretly went ashore from a submarine and gathered material on Japanese coastal fortifications and defenses in the beach area.
