ARD沈没

昭和16年12月22日夜、トラック南方で潜水艦の襲撃画面になりました。嫌な感じがしたのですが、予感は的中。ARD DublonがSS Troutに雷撃されました。一発目の魚雷は不発だったので期待してしまったのですが、2本目の魚雷はしっかり爆発してしまいました。ラバウル占領の見込みが立ったので、昨日トラックからラバウルに向けて出港させたばかりでしたが、あえなく沈没。日本に一隻しかないARDだけに、重巡を一隻失ったくらいのショックです。

前のPBEMでは、ARDのつかいどころが分からず、トラックにおいたままでした。ARDは艦船の浸水被害を修理するための浮きドックですが、アメリカのものと違い日本のこのARDは小さいので、潜水艦の浸水被害を修理するくらいしか使いようがありません。しかし、潜水艦が浸水被害を受けるのは、遠くでパトロールしている時です。大きな浸水被害がある時はシステムやエンジンにもダメージが及んでいることが多く、トラックに帰れるくらいだったら、内地の造船所に修理に向かわることになってしまいます。ARDはASの在泊している前線の基地に置くべきだと感じていました。しかし開戦後しばらく経ってそう気付いた時には、潜水艦の被害が心配で動かせなくなってしまいました。というのもARDの航海の速度は1ノットで1日に1ヘクスしか移動できないのです。そこで今回はラバウル占領の目処が立ったらすぐに移動させようと予定していたのですが、それも裏目に出てしまいました。
夜が明けてから、マニラ、メナド、ラバウルを占領しました。マニラは無防備都市状態でした。マニラよりもクラークフィールドの方が地形的に守りやすいことと、敗れると後がないマニラに対してクラークフィールドで敗れてもバターン半島に後退できることの二点で、ルソン島でなるべく長く抵抗するには、マニラを放棄してクラークフィールドに防衛戦をはる方が有利だと言われていました。最近、フォーラムのAARセクションにほとんど目を通していませんが、マニラ放棄は定跡化しているようですね。
