gun and the remote control system of one 40mm gun were destroyed. [Illustration: Department of Defense Photo (USMC) 60616 _While Marine antiaircraft artillery dealt with air raids, 155mm Long Toms were fired at targets some eight miles or more away round-the-clock, in all weather, taking a toll of the defenders._] On 5 July, a detachment of 52 men with four 40mm guns and four .50-caliber machine guns under the command of First Lieutenant John R. Wismer moved to Zanana Beach on New Georgia to provide antiaircraft and beach defense protection for the 43d Infantry Division which had landed in that area.

Hiatt translated into firing data on Rendova._ Department of Defense Photo (USMC) 60596 ] Major naval surface actions occurred on 12 July as the U.S. Navy intercepted Japanese destroyers and cruisers attempting to resupply forces on Vila and Munda. The ships’ gunfire, sounding like massive thunder and looking like a lightning storm, permitting little sound sleep, was observed from Rendova. The next day, a 90mm battery, three searchlights, and a light antiaircraft detachment arrived from the 11th Defense Battalion. The 90mm battery was staged on Kokorana until the 9th Defense Battalion displaced to New Georgia, then it went into firing positions. Light antiaircraft guns were positioned on both Kokorana and Rendova. Marines from the 11th Defense Battalion assisted the 9th in manning the radars and the 11th’s sound locator supported Battery E.

A detachment of 22 men with one 40mm gun, one twin 20mm gun, and two .50-caliber machine guns from the 9th Defense Battalion under First Lieutenant Colin J. Reeves, went to Laiana Beach on New Georgia to defend the landing site.
