Note 18 — Chapter II · The Nature of the Target

After his arrival in Australia in March 1942, General MacArthur had maintained radio contact with Corregidor until 6 May, but because of conditions in the Philippines radio communication with other parts of the Islands was all but impossible.18 Before its fall, Corregidor maintained radio contact with military commanders on the other islands. Afterward, a few men escaped and made their way to Australia. The sum of information they brought was not large, but it included the welcome news that guerrilla units were in existence all over the Islands. In the summer of 1942 General Headquarters began to receive messages from the guerrillas in the Philippines, though at first General MacArthur was not sure that the messages actually came from the guerrillas.
