This thesis deals with the life and career and intimate life of Francis Carroll Grevemberg, an antiaircraft World War II officer from New Orleans, Louisiana. Grevemberg joined the Louisiana National Guard in 1932 and began his military career in the midst of the Great Depression. In the reorganization of the U.S. Army before World War II, the War Department transformed Grevemberg's cavalry regiment into a coastal artillery battalion with antiaircraft capability. During World War II, Grevemberg saw continuous action in the North Africa, Italy and Southern France. He regularly wrote letters from battlefields to his wife Dorothy. These letters provide a important window into a young officer's feelings, thoughts and affection in the unfolding of World War II. They are documents of a soldier's emotional release during times of crises. Lt. Col. Grevemberg is a rare, World War II antiaircraft artillery officer who took part and survived five amphibious landings in the Mediterranean.
