On 21 May, the battleship arrived off Cienfuegos, Cuba, with the Flying Squadron to blockade the Cuban coast. After a return to Key West for coal, "Texas" arrived off Santiago de Cuba on 27 May. She patrolled off that port until 11 June, when she made a reconnaissance mission to Guantánamo Bay in support of the Marine landings there. The next day the "Texas" landed three field pieces and two M1895 Colt–Browning machine guns at the request of the Marine expeditionary commander, Lt. Col. Robert W. Huntington. For the next five weeks, the "Texas" patrolled between Santiago de Cuba and Guantánamo Bay. On 16 June, the warship joined the cruiser for a bombardment of the fort on South Toro Cay in Guantánamo Bay. The two ships opened fire just after 14:00 and ceased fire about an hour and 16 minutes later, having reduced the fort to impotency.
