と戦闘力は優っているのにこちらに大きな損害が。おそらく米軍の戦車相手に有効な対戦車火器が不足していると思われます。陸軍の速射砲大隊の派遣を考慮したほうがいいのかもしれません。翌12日も地上部隊が攻撃に出ましたが、

とやはり戦車相手に苦戦している模様です。これ以上の攻撃は損害を増やすだけと判断し、上陸地点への攻撃を控え、遅滞戦闘に徹することとしました。

12個師団他多数の兵力を投入しているだけあり、戦闘力比は日本側優位です。陣地がしっかり構築されているため、損害は出ていますが、中国軍にもダメージは与えており、じっくり攻略することは可能でしょう。

じっくりと押し込んで中国軍の陣地を破壊しつつあり、あと1,2回の総攻撃で陥落するものと思われます。

時間はかせげていますが、やはり戦車への対応が難しいようです。
42年はソロモン諸島方面で守備を固めて時間を稼ぐ間に、中国やインド方面での陸軍の攻勢の成功を待つ作戦になりそうです。今のところ戦車に苦戦している以外は順調ですがはたしてどうなるか…。
