引き続き飛行場を使用不能とします。翌17日は特筆すべき戦闘なし、ただしこの頃から、ソロモン諸島方面の最前線航空基地であるムンダへの空襲が激化しています。原因は前線の航空隊を機種改変したため一時的に稼働航空機が減少したことで、なぜかAIプレイヤーはそれを察知して猛空襲を仕掛けてきます。連日周辺の基地と合わせてゼロ戦が迎撃に上がっているのですが、B-24相手ではあまり撃墜できず、徐々に基地を破壊され、稼働ゼロ戦も減少しています。海軍は搭乗員数も限りがありますので、こちらの方面にも陸軍の戦闘機隊を進出させたいところです。

左側の基地のダメージ表示が徐々に溜まっています。

ゼロ戦は最新の52型に改編したのですが、それ以降空襲を受けて地上撃破される機数が増加、この日は稼働6機です。

18日、この日は中国戦線で成都で地上戦。

無事攻略しました。これで重慶流入する物資の量を減らせるはずです。21~26日は特筆すべき戦闘なしでした。ただし26日、ツラギ島への補給の必要が生じているのと、ムンダへの爆撃が続いていることもあり、大規模な作戦を行うこととしました。

図のように、重爆撃機の出撃拠点と思われるサンタクルーズ諸島の飛行場を戦艦で砲撃して爆撃機の行動を妨害するとともに、輸送船団へはエアカバーを空母機動部隊を展開することで行うこととします。さらに敵の反撃が少なければ、ムンダの飛行場修理を意図して設営部隊のムンダへの輸送も行うこととします。

27・28日は特筆すべき戦闘なし。29日はガダルカナル島付近に接近した機動部隊に周辺島嶼の基地から航空散発的な攻撃があり、これを直掩機が撃退。さらに発見した艦船を次々攻撃。

魚雷艇が警戒していたようですが、これを排除し砲撃。敵航空機に損害を与えるとともに、数日間出撃を困難にしたものと思われます。この砲撃と前日の航空戦の効果か、この日はこの方面では航空攻撃は受けず、こちらの機動部隊も攻撃範囲に敵艦船を発見できませんでした。翌31日は特筆すべき戦闘ありませんでした。最後に9月1日時点の戦況図、まずは中国方面。

重慶をほぼ孤立させていますが、凄まじい大兵力が守っているため、主力が到着しても落とせるかわかりません。そのため敵の物資を奪って戦闘力を減らすために、工場に爆撃を行っています。続いてベンガル湾方面。

カルカッタ占領と守備隊の掃討は完了。周辺地域の拠点も次々落としており、図中赤線まで前線を押し込んでいます。。戦力をカルカッタに集中していたのか、まともに守備がいない拠点もあり、空挺部隊による攻略も進み非常に進撃ペースは速いところです。当面はデリーとマドラスにそれぞれ進撃しつつ、適宜航空基地を前進させていきます。うまくいけばインド全土の占領も見えてきているところです。最後にソロモン・ニューギニア方面。

こちらは地上戦は停滞していますが、航空戦は2か所で消耗戦が生起しています。特に中部ソロモン方面は先ほど書いたようにムンダ基地への空襲が激しく、それを迎撃する戦闘機隊も消耗を強いられています。とりあえず輸送作戦も兼ねて機動部隊の展開と基地への戦艦による砲撃を実施したので、なんとかムンダ基地の態勢を立て直したいところです。

9月からの戦況も、太平洋方面で連合国に出血を強いつつ、インドで進撃を続ける展開になりそうです。

陣地をさらに破壊されたので、いよいよ限界が近いように思われます。

ここで8月1日時点の戦況図。まず中国方面。

現在四川盆地の一角を先鋒が攻略、主力を集結させつつ、まずは成都を攻略し工業力を削いでいきます。続いてベンガル湾方面。

現在カルカッタに主力が集結、敵も複数の師団がいますが徐々に攻略できているのは書いてきたところです。さらに敵の部隊が散発的に増援に来ていますので、戦車第2師団がそれらを撃破して阻止しているところです。続いてマーシャル諸島方面。

マキン島で日本軍は苦戦していますが、この方面で中心拠点であるクワジャリンまではまだありますので、もうしばらくは時間が稼げそうです。

8月は太平洋方面での連合国との戦闘がどのようになるかというところが注目です。
