I had decided almost a week ago in terms of game time that an attempt on Mersing might potentially shorten the Malayan campaign. Today is the day to put that thinking to the test. I’m certain that Force Z will come out to play. Will I get troops ashore and will I get enough to force the issue?

Ise is in dire straits. She nearly uncontrolled, seawater eating away at her stability and fires raging. There will be an attempt to make it to Kuantan and hope that an inordinate number of enemy submarines do not finish her off. Slim chance of success but the order is to try and save her. Screen shot at the end showing how perilous is her situation.

These 3 veterans took to the field late in the piece and covered themselves in glory. Repulse is still packing a punch and got in enough hits that only one is likely to survive. After 2 big battles in 2 days this is the first torpedo out of the scores which were unleashed that managed to make a hit. Hopefully it was more than just a belt armour hit… I can’t remember now what wording came up with the hit happened.
