The Army Medical Department, 1865-1917, is the third of four planned volumes that treat the time of revolutionary change in the organization of the U.S. Army and in medicine. Mary C. Gillett traces major developments for the Medical Department-from its rebirth as a small scattered organization in the wake of the Civil War, through the trials of the Spanish-American War and the Philippine Insurrection, to the entrance of the United States into World War I.
