As the United States entered the Second World War, the role and organization of the Army mushroomed almost immediately. In the Pacific, the Hawaiian Department also expanded. By 1944, the command headquarters here in Building 13 (where the Gazebo now stands) at Fort Shafter no longer served the needs of the command. Construction of a new headquarters started on 10 May 1944 and was completed in the remarkably short time of 49 days during 1944. The building was later named for the commanding general of the period, Lieutenant General Robert Richardson. During World War II, this building became known as the “Pineapple Pentagon” and was the site of Army logistical planning for the battles in the Pacific Theater during the latter years of the war. Today, it serves as the headquarters for U.S. Army Pacific.

USARPAC Patch / Click For More InformationThe unit insignia of the U.S. Army, Pacific, is depicted in the entrance walkway to Richardson Hall. Worn by American Soldiers of the Pacific since 1944, the insignia depicts a red arrow, a blue field, and white stars.
The red arrow denotes the valor and self-sufficiency of the forces of the command area. The blue field represents the vast expanse of the command area. The white stars ... the North Star, the Big Dipper, and the Southern Cross ... locate the command headquarters.

By adding up various combinations of the stars, we arrive at a key date in both the history of America’s Army in the Pacific and the United States ... December 7, 1941, the date of the attack on Pearl Harbor. more information

Left and right of the outside entrance to the building are two bronze panels containing the insignia of all divisions and units that trained and fought in the Pacific Theater in World War II. One panel also commemorates beloved journalist Ernie Pyle, killed while serving with Soldiers of the Pacific in April 1945. Technical Sergeant William Marks Simpson, a renowned designer and sculptor of Baltimore, constructed these panels. In 1930, Simpson won the Prix de Rome, one of the most coveted awards available to students of sculpture. Before entering the Army during the War, Simpson graduated from the Virginia Military Institute and also designed several U.S. coins and served as the director of the Rinehart School of Sculpture. During an inspection visit to Guadalcanal, General Richardson’s deputy, Major General Clark L. Ruffner discovered then Sergeant Simpson working as a muleskinner with the Army in Guadalcanal.

The mural in the lobby of Richardson Hall, painted in oil, depicts army infantrymen intraining onOahu during World War II. Entitled “Marching Men,” artist/soldier Master SergeantWilliam R. Domaratius of New York City painted the scenes from 1944 to 1945. The artist, who served as an artilleryman during the Pacific campaigns, used live models and it took him four to seven months to complete the mural. The entire painting covers an area of approximately 650 square feet and shows infantrymen marching through the rain and heat of jungle terrain to combat. Master Sergeant Domaratius used the terrain of the Army’s jungle training area, then located near Kahuku on the windward side of the island. Domaritius did not sign his name to his work, although he may have something of himself that is even more important. In the section depicted here, the Soldier looking directly at the viewer bears a striking physical resemblance to the artist.

Commanding General, Lieutenant General Robert C. Richardson, Jr., commissioned the projects for both the panels and the mural so that the men and officers in his command would have it as an inspiration and driving force in the war.

Also on display in the lobby are the battle flags, campaign streamers, and an exquisite Medal of Honor exhibit that pays homage to Pacific Theater Soldiers who received the nation's highest honor for heroism and bravery in battle. The Army installed a touch screen interactive display that allows visitors to learn about America's Army in the Pacific from the vantage points of the past, present, and future and see exactly where today's Soldiers and their units are deployed around the world in support of the Global War on Terrorism.
