The Army Attack: Kwajalein
In accordance with the overall campaign plan for the seizure of the Marshall Islands, the Army’s attack on Kwajalein Island at the south end of the atoll began in exact synchronization with the Marine assault in the north. The same softening-up process was used on D-day, 31 January, with a large force of warships and planes pouring on a blanket of high explosive. The Navy, for instance, fired 7,000 shells. Because of the location of the islets immediately surrounding its main objective, the 7th Infantry Division was able to follow a plan identical to the Marines, with the 17th Infantry Regiment clearing the way for placement of close-by supporting artillery. The 145th Field Artillery Battalion then proceeded to inundate the target with 28,000 rounds.
