The Invisible War

While the Second World War raged in Europe, demanding most of Canada's military effort, an equally fierce war with Japan was going on in the Far East. Army, navy, and air force signals units in Canada kept watch on the enemy's vital radio communications. To be more effective, Number One Canadian Special Wireless Group of the Royal Canadian Signals Corps was formed to go to the Southwest Pacific war theatre for close-in radio eavesdropping. Murray describes the often zany career of the only complete signals unit Canada sent to the War in the Pacific, and the significant part it played in the Allied signals intelligence operation known as «Magic.»
