It was after the US Civil War, the nation was undergoing a period of healing from the "brother against brother" conflict. Fort Whipple, one of the original fortifications among the Defenses of Washington had continued on after all the other nearly 70 fortifications were abandoned. The first Chief Signal Officer, General Albert J. Myer had brought his Signal Corps School to Arlington Heights. It was 1880 when the name changed to Fort Myer in his honor. In August 1886 the US Congress designated Fort Myer a military station and the Signal Corps School vacated. With a vision in mind of turning Fort Myer into a Cavalry Show Case, LTG Phillip H Sheridan requested that it become a cavalry post. It was nearly a year later in July 1887, when Troop B of the 6th Cavalry from Fort Lewis, Colorado and Troop B of the 4th Cavalry from Fort Hauchuca, Arizona arrived. Major James Biddle of the 6th as commanding officer. The cavalry had arrived and would spur a growth in permanent buildings including troop barracks, a riding arena, new stables. For several decades, the cavalry would provide the defense of the US Capital and ceremonial support in and around Washington, DC including final honors support at Arlington National Cemetery. In time the US Army would establish the Remount Service and nearly 1,500 horses would occupy the acres of Fort Myer. Over 200 Historical photographs from the 1860s to the 1960s are within the book "Images of America - Fort Myer" that chronicle the emergence of this historic unique US Army Post.
