11日、前日の空振りを受けて、ルンガ沖の機動部隊は護衛の巡洋艦の一部を切り離し、上陸地点に突入させることとします。機動部隊本隊は引き続き周辺で艦載機出撃の機会を伺います。その結果、

と、上陸地点の船団を突入した巡洋艦が撃沈。さらに周辺海域の増援船団を艦載機で撃破しました。2か所合わせて上陸部隊に大きな打撃を与えたはずです。護衛の艦艇が貧弱なのは、AIの上陸作戦下手を示しているところです。一方ルンガでは、上陸した敵部隊が攻撃を仕掛けてきました。

と海兵連隊が上陸していたようですが、後続の船団を撃破しましたので、増援の陸戦隊が到着すればこちらも殲滅できるでしょう。

12日は機動部隊をさらに南下させ、退避するであろう残りの船団を追撃、この日も大打撃を与えました。

13日は、連日の戦闘で魚雷を使い切った空母も出たことから、いったんルンガ近隣のツラギに艦隊を集結させることとしました。トラックから出撃させた弾薬を満載した貨物船や燃料を積んだタンカーの外、空母飛鷹・隼鷹も来ていますので、米軍のさらなる来週に備えて、態勢を整えることとします。

14日は引き続きツラギへの移動を続けているほか、逆上陸部隊の第1陣がルンガに上陸を開始。

1st USMC Field Artillery Battalion Wiped Out at Lunga by attrition!!!

全滅には追い込めませんでしたが、砲兵部隊が消耗で崩壊したようです。流石に米海兵隊は粘り強いですが、あと一歩といったところでしょう。

7月はソロモン南部の戦いが焦点になりそうですが、今のところ連合国に大きな被害を与えられていますので、引き続き来襲する連合国軍を撃破していきたいところです。
