美军在冲绳岛的登陆之初,一直比较顺利。1945年4月4日,美军陆战第1师和陆战第6师攻占中部地区、将日军分割为南北两部分后,美军就兵分两路:海军陆战队第3军向东北和北部推进,陆军第24军向南部推进。28日,冲绳岛的中部、北部和伊江岛均被美军攻占。但是,陆军第24军对南部地区的进攻却非常艰难。因为日军在冲绳岛的主力就部署在南部,而且充分利用悬崖峭壁、深沟高谷等险峻地形构筑起坚固隐蔽的防御工事,所以美军进展极其缓慢。
The landing of the U.S. military in Okinawa has been relatively smooth. On April 4, 1945, the first division of the U.S. Marine Corps and the 6th Marine Division captured the central region. After the Japanese were divided into two parts, the two sides split into two parts: the 3rd Marine Corps unit advanced to the north and northeast Army 24th Army to the south. On the 28th, Okinawa’s central, northern and Iijima islands were captured by U.S. forces. However, the 24th Army Army attack on the southern region is very difficult. Because the Japanese troops deployed themselves in the southern part of Okinawa and made full use of the steeply hidden fortifications on steep terrain such as cliffs and deep valleys and valleys, the U.S. military has made extremely slow progress.
