AI連合国、艦船の退避の判断が悪いので、これだけ爆撃されてなおスラバヤ港を潜水艦の拠点としようとしています。結果として米潜水艦とオランダ潜水艦を撃沈。

この日は艦が減ったのか攻撃規模の割にいまいち戦果が良くありません。

攻略成功とはなりませんでしたが、戦闘力比も両軍の損害も日本側有利。連合国は増援に送られた中国軍と現地兵の英軍中心のようですので、おそらく質や装備の差で押せているものと思われます。このまま押し切ってマンダレーを攻略したいところ。

19日、スラバヤ付近で敵艦隊を機動部隊が捕捉、

一応命中弾は出ていますが、攻撃規模を考えると不満足な戦果、特に魚雷が一発も当たらないのは。

一方ビルマ戦線ではこの日、これまでマンダレーで発生していた戦闘機同士の空戦が発生せず。どうやら地上部隊が接近したことで、マンダレーの基地にいた敵戦闘機隊が後退したため迎撃機がいない模様です。制空権がとれておらず爆撃できていなかったのですが、ここからは爆撃できそうです。マンダレーの地形は平地ですので強力な航空支援が出来るのではないかと判断し、20日から爆撃を実施。

高射砲による反撃が激しいですが、一定の戦果が上がっています。ただこれまで爆撃機の出番がなかったので、この戦線には強力な重爆隊がいません。重爆を他戦線から移動させればさらに強力な支援が実施できそうです。続いてスラバヤ付近で再度敵艦隊を機動部隊が攻撃、

運が悪かったのか前回が良すぎたのか、前回の総攻撃より戦闘力比が悪くなっています。しかし陣地は破壊できていますし、敵の戦闘部隊へのダメージも大きいと思われます。再度態勢を整えるとともに、航空支援を強化すれば確実に落とせるでしょう。

マンダレーの攻略が目前に迫っていますが、現在ジャワ島のスラバヤにも地上部隊が接近しています。この2拠点を落とせれば南方作戦終了と言っていいでしょうから、ゲーム内時間で5月中には南方作戦終了と言えそうです。
