The rest were members of the 43rd division of the Japanese imperial army, with some elements of the 47th mixed brigade, and small numbers of naval personnel. In addition to small arms and machine guns, the Japanese also possessed 36 medium tanks, and 12 light tanks. Also, present on the island were 29, 75mm mountain guns, 22 howitzers and scattered coastal artillery pieces (Crowl, 1993). American forces consisted of the 2nd and 4th Marine divisions, along with the US Army 27th division totaling 71,000 troops (Kingston, 2017). The 2nd Marines were veterans of Guadalcanal and Tarawa, with the 4th Marines and the 27th both having combat experience in the Pacific as well (Crowl, 1993). In addition to their organic weapons, US forces had tank support as well as amphibious tractors, which mounted mortars and 75mm cannons.

The defenders attempted to halt the Marines in many locations, but found themselves slowly and steadily pushed to the north end of the island. Slow moving, intense fighting continued in the rugged terrain and high ridges as the Japanese were worn down and forced to retreat into ever tighter confines. On the morning of July 7th, the defenders conducted a suicide charge into US lines, losing approx. 4,311 soldiers, effectively ending their defense of the island. On the 9th of July, the island of Saipan was declared secure (Crowl, 1993). Total Japanese losses were estimated at 30,000, with the Americans losing 14,244 dead, wounded or missing in action (History Net,
