Yuma Crossing
Immediately after the Mexican–American War in 1848, the U.S. Army built Fort Yuma here to protect travelers from Indians raiding the area. It was the center point of conflict in the Yuma War of 1850–53. From 1864–1890, the fort and nearby facilities was the main army base to support the US Army's efforts to control the Indians throughout the greater southwest.

The Battle of Iwo Jima was fought between the United States and the Japanese Empire, in February and March 1945 during the Pacific Campaign of World War II. Ground fighting on the island took place over approximately 35 days; lasting from the landings of February 19 to a final Japanese charge the morning of March 26, 1945. The U.S. invasion, known as Operation Detachment, was charged with the mission of capturing the island's airfields. The Japanese positions on the island were heavily fortified, with vast bunkers, hidden artillery, and 18 kilometers (11 mi) of tunnels.
