Operation Watchtower: Assault on the Solomons

Operation Watchtower: Assault on the Solomons

On August 7, 1942, U.S. Marines landed in the Florida Islands, a small group of islands north of Guadalcanal in the Solomon Islands. These men were the first American troops to invade enemy territory in World War II, and they were followed shortly by other Marines who landed on Tulagi and Guadalcanal. The next seven months on Guadalcanal proved to be one of the major turning points of the war.

Important naval engagements also occurred during this period, including the Battle of Savo Island, a resounding defeat for the Allies; the battles of the Eastern Solomons and Santa Cruz Islands were crucial as both sides continued to pour men, planes, and ships into the campaign. The Japanese shipped thousands of reinforcements and supplies to the island on such a regular schedule that it was dubbed the "Tokyo Express" by the Americans. Refusing to admit defeat, the Japanese bravely fought on before finally evacuating Guadalcanal in February, 1943.

As the Solomon campaign initially proved tenuous, civilian planters, miners, traders, missionaries, former government officers, and native Solomon Islanders formed a volunteer network known as the coastwatchers. The coastwatchers, by communicating information about Japanese positions, played one of the most important roles of any volunteer resistance group in the southwest Pacific campaigns during the war. Organized in and expanded from New Guinea by Eric Feldt, an officer in the Royal Australian Navy, these men secretly operated behind enemy lines, provided critical information to the Allies about Japanese troop, ship, and aircraft movements, evacuated civilians, rescued Allied aviators, and ambushed Japanese troops.

Equipped with radio transmitters, the coastwatchers were essentially human radar, and they helped Allies inflict significant defeats on Japanese naval and air forces. In the Solomons, coastwatchers were stationed on Guadalcanal, Buka, Bougainville, New Georgia, Santa Isabel, and Malaita. Most of the Japanese aircraft that attacked Guadalcanal from their bases in New Britain had to pass over New Georgia. The reports from the coastwatchers on that island were especially valuable, allowing American planes to intercept in coming bombers.The famous American naval commander, Admiral William "Bull" Halsey, remarked of these men, "The coastwatchers saved Guadalcanal and Guadalcanal saved the South Pacific."
