Operation Galvanic was a significant military campaign during World War II, specifically part of the Pacific Theater. It took place from November 20 to December 4, 1943, and aimed to capture the strategically important island of Tarawa in the Gilbert Islands. The operation involved intense fighting between American forces and the defending Japanese troops. The operation was notable for its amphibious assault, which faced challenges such as rough seas and strong enemy fortifications. Despite these difficulties, American forces successfully secured the island, marking a crucial step in the broader strategy to advance across the Pacific and ultimately defeat Japan.
