The regiment marched in the Washington, D.C. victory parade and returned to New York. All the regiments of the Irish Brigade were disbanded except the 69th, which remained part of the New York National Guard. The 69th remained a place of unity and culture for Irish Americans in the post-war years. It was called into active service in 1898 for the Spanish–American War, transported to Chickamauga, Georgia, Tampa, Florida, and Huntsville, Alabama, but it did not see combat due to the brevity of that war. In 1916, the regiment was posted to McAllen, Texas, along the Mexican border during the Punitive expedition.
