Flag of Guam
The flag of the United States territory of Guam was adopted on February 9, 1948. The territorial flag is dark blue with a narrow red border on all sides (border was a later addition). Narrow red border represents the blood that it ravaged in World War 2 and Spanish sovereignty. In the center of the flag is the coat of arms; an almond shaped emblem, which depicts a proa sailing in Agana Bay near Hagåtña, and "GUAM" colored in red letters. The shape of the emblem recalls the slingshot stones used by the islanders' ancestors. The landform at the back depicts the Punta Dos Amantes cliff on Guam. Charles Alan Pownall approved the flag's shape in 1948.
History of Guam
On June 21, 1898, the United States captured Guam in a bloodless landing during the Spanish–American War. By the Treaty of Paris, Spain officially ceded the island to the United States. Guam became part of an American telegraph line to the Philippines, also ceded by the treaty; a way station for American ships traveling to and from there; and an important part of the United States' War Plan Orange against Japan. Although Alfred Thayer Mahan, Robert Coontz, and others envisioned the island as "a kind of Gibraltar" in the Pacific, Congress repeatedly failed to fulfill the military's requests to fortify Guam; when a German warship was interned in 1914 before America's entry into World War I, its crew of 543 outnumbered their American custodians.
