1st Filipino Infantry Regiment

The 1st Filipino Infantry Regiment was a segregated United States Army infantry regiment made up of Filipino Americans from the continental United States and a few veterans of the Battle of the Philippines that saw combat during World War II. It was formed and activated at Camp San Luis Obispo, California, under the auspices of the California National Guard. Originally created as a battalion, it was declared a regiment on 13 July 1942. Deployed initially to New Guinea in 1944, it became a source of manpower for special forces and units that would serve in occupied territories. In 1945, it deployed to the Philippines, where it first saw combat as a unit. After major combat operations, it remained in the Philippines until it returned to California and was deactivated in 1946 at Camp Stoneman.

The 395th Infantry Regiment was an infantry regiment of the United States Army, part of the 99th Infantry Division during World War II. It was organized with the rest of the 99th on 16 November 1942 at Camp Van Dorn, Mississippi. During the Battle of the Bulge, the regiment—at times virtually surrounded by Germans—was one of the few units that did not yield ground to the attacking Germans. On at least six occasions they called in artillery strikes on or directly in front of their own positions. Their success in defending Höfen resulted in the 395th Infantry being repeatedly assigned to other divisions for difficult assignments during the remainder of the war, earning them the sobriquet, Butler's Blue Battlin' Bastards. The unit was inactivated after World War II, then became a reserve unit, and was redesignated as the 395th Regiment in 1999.

Battery SteeleW
Battery Steele

Battery Steele is a United States military fortification on Peaks Island, Portland, Maine in Casco Bay. Completed in 1942 as part of World War II, it is located on 14 acres (5.7 ha) on the oceanside area of the island, formerly part of the Peaks Island Military Reservation. It is named for Harry Lee Steele, who was a Coast Artillery officer during World War I. It was armed with two 16-inch MkIIMI guns and, with a 12-inch gun battery at Fort Levett on Cushing Island, replaced all previous heavy guns in the Harbor Defenses of Portland. It was built to protect Casco Bay, particularly Portland harbor, from Kennebunk to Popham Beach in Phippsburg. According to Kim MacIsaac and historian Joel Eastman in An Island at War, “Battery Steele is not only the largest gun battery built on Peaks Island, but also an example of the largest battery ever built anywhere in the United States.” In 1995, after decades of non-use, the Peaks Island Land Preserve, a community land preservation group, formed to purchase the area and forever preserve it as a public space. On October 20, 2005, the property was listed on the National Register of Historic Places. Other coast defense structures on the island include fire control towers and the counterweight for a disappearing searchlight tower.

George S. Patton slapping incidentsW
George S. Patton slapping incidents

In early August 1943, Lieutenant General George S. Patton slapped two United States Army soldiers under his command during the Sicily Campaign of World War II. Patton's hard-driving personality and lack of belief in the medical condition of combat stress reaction, then known as "battle fatigue" or "shell shock", led to the soldiers' becoming the subject of his ire in incidents on 3 and 10 August, when Patton struck and berated them after discovering they were patients at evacuation hospitals away from the front lines without apparent physical injuries.

The loss of Saipan, with the deaths of at least 29,000 troops and heavy civilian casualties, precipitated the resignation of Prime Minister of Japan Hideki Tōjō and left the Japanese archipelago within the range of United States Army Air Forces B-29 bombers.

Utah prisoner of war massacreW
Utah prisoner of war massacre

The Utah prisoner of war massacre took place after the end of World War II in Europe at midnight on July 8, 1945 at a German and Italian prisoner-of-war camp in Salina, Utah. Nine German prisoners of war were murdered and nineteen prisoners were wounded by American private Clarence V. Bertucci, who was on active duty in the camp. After a night out, Bertucci returned to camp around midnight to assume his night duty at the guard tower. Bertucci subsequently loaded the .30-caliber M1917 Browning machine gun on the tower and fired at the tents of the sleeping prisoners. After the massacre, he revealed his motivation was that, "he had hated Germans, so he had killed Germans." Six Germans were immediately killed, three died in Salina's hospital, and nineteen were wounded.
