Tagesbericht 02. Mai 1942
Feindliche U-Boote waren heute sehr aktiv, wenn auch glücklos. In zwei Fällen konnten die eigenen Schiffe den geschossenen Torpedos ausweichen. Im dritten Fall spielte wohl fehlerhafte Technik das Zünglein an der Waage. In alles drei Fällen konnten sich die Feindboote schließlich absetzen.

Im zweiten Versuch, Langsa einzunehmen, beschoss der Kreuzerverband heute erneut die niederländischen Stellungen, bevor sich der Landungsverband der Küste näherte und vor Anker ging und die Landungsboote zu Wasser lies. Diesen mal dürften die angesetzten Kräfte ausreichend sein. Im Abwehrfeuer der Küstenbatterien kam es zu Unruhe bei den Landungsbooten und ungewohnt hohen Verlusten.

In China konnten sowohl bei Sian, als auch bei Hwainan flankierende oder im rückwärtigen Raum operierende Feindkräfte geschlagen und zum Rückzug gezwungen werden. So lästig diese Feindtaktik auch ist, das Oberkommando hofft, dass gerade die hohen Feindverluste bei Ausrüstung und schweren Waffen die Chinesen mittelfristig spürbar schwächen werden.
