Bowser had a photographic memory and could report every word of the documents she saw at the "White House." In recognition of her intelligence contributions, Bowser was inducted into the US Army Intelligence Hall of Fame at Fort Huachuca, Arizona, on 30 June 1995. Tubman's triumphs Harriet Tubman, another black woman involved in intelligence collection for the Union, is well known for her activities with the underground railroad. Her intelligence activities, however, are well documented. Tubman, often referred to by her contemporaries as "Moses," is best known for the numerous trips she made into the south to free relatives and friends and bring them to safety. Her last trip took place in 1860. With the advent of the fighting, she spent the early years of the war assisting with the care and feeding of the many slaves who had fled to Union-controlled areas.

For example, her part in a June 1863 Union raid up the Combahee River in South Carolina is well documented. Tubman had conducted spy missions into the area, identified enemy supply areas, and reported weaknesses in Confederate troop deployments. In late May, Gen. David Hunter, commander of all Union forces in the area, asked Tubman to personally guide a raiding party up the river. On the evening of 2 June, Tubman led Montgomery and 150 of his men up the river past Confederate picket lines. In a swift raid, taking the Confederates by surprise, the Union forces destroyed several
