Signal Corps Sleeve Insignia

In 1858, the Army expressed interest in Albert J. Myer’s system, and after extensive testing, the United States Signal Corps was born, with Myer appointed as major and chief signal officer. At the outbreak of the Civil War, Myer was tasked with recruiting and training officers and establishing schools of instruction. By the end of the war, the Signal Corps consisted of almost 300 officers and 2,500 soldiers.
