On June 22, 1898, soldiers of the 3d Infantry Regiment arrived in Santiago Harbor, Cuba.

 The Regiment started their journey when they departed Fort Snelling, MN by train on April 19. They arrived in Mobile, AL two days later having traveled over 1,400 miles. The Regiment trained in Mobile for six weeks, until it was transferred to Tampa, FL on June 13. Upon reaching Tampa, it was assigned to General Shafter’s force en route to Cuba. Once ashore in Cuba, the Regiment is placed in Brigadier General Bates’ Independent Brigade, and placed in reserve at El Pozo, the Headquarters of the US Army Fifth Corps. By July 1, the Regiment is placed into action as part of the Siege of Santiago.
