🏝️ Aleutian Islands Campaign: The Only WWII Land Battle on US Soil

The Aleutian Islands campaign, led by US and Canadian forces, was a significant military operation during World War II. It involved the islands of Attu and Kiska, marking the only land battle fought on US soil apart from the attack on Pearl Harbor. The operation included the invasion of Kiska, known as Operation Cottage, which was one of the most peculiar actions of the war. The campaign began in June and July 1942 when the Japanese, led by Admiral Yamamoto, invaded the islands as a diversion from their Midway campaign and to prevent the US from using the islands as a base to attack Japan. The islands' capture was relatively easy for the Japanese, who then started building airfields and fortifications. The US was determined to liberate the islands for both strategic and national pride reasons. The Alaska Defense Command, initially small, quickly expanded its forces. The first target was Attu, which was successfully invaded in May 1943, despite fierce resistance from the Japanese and high American casualties. The operation was marked by unsuitable equipment and lack of combat experience among the American soldiers. The lessons learned from the Attu invasion influenced the approach to Kiska, where reconnaissance indicated a heavily fortified island with an estimated 10,000 Japanese soldiers.

🚒 Operation Cottage: The Bizarre Liberation of Kiska Island

Operation Cottage, the invasion of Kiska, was a complex and challenging military endeavor. The operation involved over 34,000 soldiers from the US 7th Infantry Division and the 1st Special Service Force, alongside 5,300 Canadians from the 13th Royal Canadian Infantry Brigade. The invasion began on August 15, 1943, with troops landing on the island's middle part, facing immediate logistical issues due to poor tide calculations. Despite the challenges, the landing was unopposed, as the Japanese had already retreated, unbeknownst to the Allies. The Allied forces, inexperienced and disoriented by the dense fog and cold winds, advanced inland, encountering abandoned Japanese positions and booby traps. The operation was marred by friendly fire incidents and minefield casualties. The destroyer USS Abner Reid struck a mine, resulting in significant loss of life. The troops, on edge due to anticipation of a Japanese counterattack, were further panicked by rumors of snipers and soldiers in hiding. After three days of searching, it was discovered that the Japanese had stealthily evacuated the island after the Battle of Attu, leaving the island unoccupied. The operation, despite being successful in liberating the island, was criticized due to the high number of friendly fire casualties and the unnecessary struggle against an already abandoned enemy position. The experience from Operation Cottage provided valuable lessons for future amphibious assaults.
