By the beginning of 1944, United States Marine forces had already made a dramatic start on the conquest of areas overrun by the Japanese early in World War II. Successful American assaults in the Southwest Pacific, beginning with Guadalcanal in the Solomon Islands in August 1942, and in the Central Pacific at Tarawa in the Gilbert Islands in November 1943, were crucial campaigns to mark the turn of the Japanese floodtide of conquest. The time had now come to take one more decisive step: assault of the islands held by Japan before 1941.
These strategic islands, mandated to the Japanese by the League of Nations after World War I, were a source of mystery and speculation. Outsiders were barred; illegal fortifications were presumed; yet any Central Pacific drive towards Japan’s inner defense ring had to confront these unknowns. The obvious target to begin with was the Marshall Islands. As early as 1921 a Marine planning officer had pinpointed their geographic significance.
In May 1943, the Combined Chiefs of Staff decided to seize them. This difficult assignment fell to Admiral Chester W. Nimitz who bore the impressive titles of Commander in Chief, Pacific, and Commander in Chief, Pacific Ocean Areas (CinC-Pac/CinCPOA), based at Pearl Harbor in Hawaii. He turned to four very capable men who would carry out the actual operation: three admirals who were experts in amphibious landings, fast carrier strikes, and shore bombardment, and Major General Holland M. Smith, who was the commanding general of the Marines’ V Amphibious Corps and now also would be Commanding General, Expeditionary Troops. It was he who would command the troops once they got ashore. Original cautious plans for steppingstone attacks starting in the eastern Marshalls were modified, and the daring decision was made to knife through the edges and strike directly at Kwajalein Atoll in the heart of Marshalls’ cluster of 32 atolls, more than 1,000 islands, and 867 reefs.
