It is the westernmost point and territory of the United States, reckoned from the geographic center of the U.S. In Oceania, Guam is the largest and southernmost of the Mariana Islands and the largest island in Micronesia. As of 2022, its population was 168,801. Chamorros are its largest ethnic group, but a minority on the multiethnic island.

The Mariana and Palau Islands campaign, also known as Campaign Plan Granite II, was an offensive launched by United States forces against Imperial Japanese forces in the Pacific Ocean between June and November 1944 during the Pacific War. The campaign consisted of Operation Forager, which captured the Mariana Islands, and Operation Statemate, which captured Palau. Operation Causeway, the invasion of Taiwan was also planned but not executed. The offensive, under the overall command of Chester W. Nimitz, followed the Gilbert and Marshall Islands campaign and was intended to neutralize Japanese bases in the central Pacific, support the Allied drive to retake the Philippines, and provide bases for a strategic bombing campaign against Japan.
Holland McTyeire "Howlin' Mad" Smith, KCB was a general in the United States Marine Corps during World War II. He is sometimes called the "father" of modern U.S. amphibious warfare. His nickname, "Howlin' Mad" Smith, had been given to him by his troops in the Dominican Republic in 1916.
Apra Harbor, also called Port Apra, is a deep-water port on the western side of the United States territory of Guam. It is considered one of the best natural ports in the Pacific Ocean. The harbor is bounded by Cabras Island and the Glass Breakwater to the north and the Orote Peninsula in the south. Naval Base Guam and the Port of Guam are the two major users of the harbor. It is also a popular recreation area for boaters, surfers, scuba divers, and other recreationalists.
The Battle of Guam was the American recapture of the Japanese-held island of Guam, a U.S. territory in the Mariana Islands captured by the Japanese from the United States in the First Battle of Guam in 1941 during the Pacific campaign of World War II. The battle was a critical component of Operation Forager. The recapture of Guam and the broader Mariana and Palau Islands campaign resulted in the destruction of much of Japan's naval air power and allowed the United States to establish large airbases from which it could bomb the Japanese home islands with its new strategic bomber, the Boeing B-29 Superfortress.
Piti is a village located on the central west coast of the United States territory of Guam. It contains northern and eastern coastlines of Apra Harbor, including Cabras Island, which has the commercial Port of Guam and the island's largest power plants. Piti was a pre-Spanish CHamoru village and, after Spanish colonization, became the primary port town on Guam. The town was largely destroyed during the 1944 liberation of Guam and the population relocated during the wartime construction of Apra Harbor.
When World War II broke out the United States Naval Construction Battalions (Seabees) did not exist. The logistics of a two theater war were daunting to conceive. Rear Admiral Moreell completely understood the issues. What needed to be done was build staging bases to take the war to the enemy, across both oceans, and create the construction force to do the work. Naval Construction Battalions were first conceived at Bureau of Yards and Docks (BuDocks) in the 1930s. The onset of hostilities clarified to Radm. Moreell the need for developing advance bases to project American power. The solution: tap the vast pool of skilled labor in the U.S. Put it in uniform to build anything, anywhere under any conditions and get the Marine Corps to train it. The first volunteers came skilled. To obtain these tradesmen, military age was waived to age 50. It was later found that several past 60 had managed to get in. Men were given advanced rank/pay based upon experience making the Seabees the highest paid group in the U.S. military. The first 60 battalions had an average age of 37.
The Japanese occupation of Guam was the period in the history of Guam between 1941 and 1944 when Imperial Japanese forces occupied Guam during World War II. The island was renamed Ōmiya-Jima.
Orote Field is a former air base in the United States territory of Guam built by the Empire of Japan with Chamorro forced labor during the Japanese occupation of Guam (1941-1944). It is separate from the Marine Corps amphibious airplane base at located at Sumay village that was operational from 1921 to 1931. Following the liberation of Guam in 1944, the U.S. military repaired the field for further use in the Pacific War.
Naval Base Guam is a strategic U.S. naval base located on Apra Harbor and occupying the Orote Peninsula. In 2009, it was combined with Andersen Air Force Base to form Joint Region Marianas, which is a Navy-controlled joint base.
The Orote Peninsula is a four kilometer-long peninsula jutting from the west coast of the United States territory of Guam. A major geologic feature of the island, it forms the southern coast of Apra Harbor and the northern coast of Agat Bay. Its tip, Point Udall, is Guam's westernmost point and also the United States' westernmost point by travel, not longitude. The peninsula historically was the site of the important Chamorro village of Sumay, as well as Fort Santiago of the Spanish colonial period. In modern times, the peninsula is politically in the village of Santa Rita, but it is controlled in its entirety by Naval Base Guam.
Kongō Maru (金剛丸) was an 7,043 gross register ton passenger-cargo ship built by Harima Shipbuilding Company in Japan for Kokusai Kisen Kabushiki Kaisha in 1935. She was requisitioned by the Imperial Japanese Navy during the Second World War and converted to an armed merchant cruiser.
Joint Region Marianas' mission is to provide installation management support to all Department of Defense components and tenants through assigned regional installations on Guam and the Northern Mariana Islands in support of training in the Marianas; to act as the interface between the Department of Defense and the civilian community; to ensure compliance with all environmental laws and regulations, safety procedures, and equal opportunity policy; and perform other functions and tasks as may be assigned.
George Johnson McMillin was a United States Navy rear admiral who served as the 38th and final naval governor of Guam. He served as an officer during four separate conflicts: World War I, the occupation of the Dominican Republic, the United States occupation of Veracruz, and World War II. He served on the staff of both the Naval Academy and the Naval War College as well. He is most remembered as the commander who surrendered Guamanian forces to a much larger Japanese force during the First Battle of Guam, only the second battle of World War II involving the United States. He had previously evacuated all but one civilian American citizen from the island and attempted to rebuild defenses after a strong typhoon devastated the island the year before. On December 8, 1941, Japanese forces invaded Guam and McMillin surrendered two days later. He spent the rest of the war at various Japanese prisoner of war camps.

He was incarcerated by the Japanese as a prisoner of war. He was promoted to brigadier general during captivity and retired from military service in 1946. He is buried at the Golden Gate National Cemetery in San Bruno, San Mateo County, California.
The Guam Insular Force Guard was a former military formation of Guam. It was created in 1901.
Sumay, also Sumai, was a village on the United States territory of Guam. It was located on the north coast of the Orote Peninsula along Apra Harbor. It was inhabited by Chamorro people before contact with Europeans. Sumay became a prosperous port town serving whalers and other sailors in the 1800s and the second most populous settlement on Guam after Hagåtña, the capital of the Spanish Mariana Islands. Following the Capture of Guam by the United States in 1898, the village was the site of Marine Barracks Guam. In the early 1900s, it was a link for two firsts connecting the United States and Asia: the first submarine communications cable for telegraph and the China Clipper, the first air service. After the Japanese invasion of Guam in 1941, the residents were evicted and the village turned into a Japanese military garrison. Sumay was leveled during the U.S. liberation of the island in 1944. The U.S. military prohibited the residents from returning, relocating them to the hills of nearby Sånta Rita-Sumai. In 1948, the U.S. military exercised eminent domain and took all private and commercial property at Sumay. Its former location is now on Naval Base Guam.
Liberation Day on the U.S. territory of Guam is an annual commemoration of the invasion by U.S. military forces on July 21, 1944, which ended the Japanese occupation that had begun in 1941. Begun in 1945, it is Guam's largest celebration. Festivities include a queen contest, summer carnival, fireworks display, and mile-long parade on Marine Corps Drive in Hagåtña from Adelup to Paseo de Susana, as well as solemn memorials and visits to massacre sites. It is organized by the Guam Island Fair Committee.
