General Walter Krueger needed the most up-to-date intelligence against a strong and lethal opponent. For the U.S. Army fighting the Japanese in WWII, good intel could avert a catastrophe and save thousands of lives. Given the nature of the war, it would be a dangerous job.
Krueger sought volunteers who would go deep behind enemy lines to get troop strengths, numbers, and unit types, as well as information about their locations and destinations.
To be an Alamo Scout required problem-solving skills and quick-thinking. It demanded physical strength – not necessarily athleticism, but the ability to withstand the rigors of long marches and missions. And of course, it required observation skills, land navigation, and cover and concealment. Anyone who expressed a burning desire to "kill Japs" was turned away.
The Scouts' rigorous training center at Kalo Kalo on Fergusson Island, New Guinea also served as a base of operations. After six weeks of intense training, 700 men dwindled down to 138, who formed 6- to 7-man fire teams. There were no prescribed uniforms and they didn't pay much attention to rank.
What started as an elite recon mission soon became an intelligence asset that could coordinate large-scale guerrilla operations in the Philippines. Alamo Scouts could move 30 or 40 miles in a day with little rest or food.
Their first mission came in February 1944: to get intel on the Japanese on Los Negros in the Admiralty Islands. No one knew if there was a Japanese presence there; it was presumed to be evacuated. An Alamo Scout team was landed by a PBY Catalina. Once there, they had 48 hours before the 1st Cavalry Division landed.
Alamo Scouts came to within 15 feet of Japanese lines on Los Negros. Not only were the Japanese there, they were well-fed and well-armed--an estimated 5,000 troops remained in garrison. After a few close calls with unknowing Japanese fighters, the Scout teams were able to report enemy numbers to the invading forces, who successfully overtook the island.
The invasions of Madang, Wewak, Sarmi, Biak, Noemfoor, Sansapor and Japen Island were all subsequently preceded by recon operations conducted by Scout teams. They also liberated 66 Dutch POWs from their prison camp on New Guinea.
Their most famous feat was their recon and support for the 6th Rangers during the raid on the Cabanatuan POW Camp in the Philippines in 1945. The two Army units, along with Filipino partisans, liberated 511 prisoners and captured 84 Japanese POWs.
To get the most accurate information, Alamo Scouts approached to within a hundred yards of the camp's fence dressed as Filipino rice farmers. The recon operation was never discovered.
Alamo Scouts were also to be used preceding the Allied invasion of the Japanese Home Islands, but the unconditional surrender of all Japanese forces in 1945 ended their reconnaissance mission. They were added to the occupation Army and then disbanded later that year.
Over their careers, the Alamo Scouts performed 106 missions deep in enemy territory over 1,482 days of sustained combat. Not one was ever killed or captured, though two were wounded in the Cabanatuan Raid. In 1988, the Alamo Scouts were added to the U.S. Army's Special Forces lineage and its veterans were acknowledged with the Special Forces tab.
