In short: Lieutenant General Simon Bolivar Buckner Jr. led the Tenth Army during the brutal Battle of Okinawa. Known for his uncompromising leadership and rigid discipline, he became the most senior U.S. military officer lost to enemy fire during the war when a Japanese artillery shell struck his position in June 1945.

Born in 1886, Simon Bolivar Buckner Jr. was the son of a Confederate general and namesake of the South American liberator Simón Bolívar. After graduating from West Point in 1908, he spent nearly two decades in military education and training roles, earning a reputation for severity and sound judgment. By 1940, he had risen to brigadier general and was tasked with fortifying Alaska. During his command there, he oversaw the Aleutian Islands campaign, including the recapture of Attu and the Kiska Expedition, where Allied forces famously bombarded a deserted island after the Japanese garrison had secretly evacuated under cover of fog.

In 1944, Buckner was transferred to Hawaii to organize the Tenth Army for the invasion of Okinawa. The battle, which began on April 1, 1945, became one of the most protracted and lethal conflicts in American history. Buckner favored a direct, frontal assault strategy that, while successful, resulted in heavy American casualties and significant civilian losses as the fighting moved into the southern part of the island. His command style was marked by a stern, sometimes controversial, approach to his troops and subordinates, including his vocal objection to the deployment of African American soldiers in Alaska.

Buckner's death occurred on June 18, 1945, while he was visiting a forward observation post near Ibaru Ridge. Despite his attempt to maintain anonymity by wearing an unmarked helmet, he was struck by fragments from a 47mm Japanese artillery shell. He died shortly after at an aid station. Posthumously promoted to four-star general in 1954, his legacy persists through numerous military installations and landmarks, including the Buckner Building in Alaska and Camp Buckner at West Point, serving as a reminder of the high human cost of the Pacific Theater.
