Malaya: Allied ground forces in central Malaya prepping to withdraw southward to form a defense around Johore Bahru. Some units will begin moving southward on the 12/21 game turn, the remaining Allied LCU’s in central Malaya to begin their southward movement over the next 1-2 days.
Plans are to divert several of the Allied combat LCU’s leaving central Malaya to reinforce 22 Australian Brigade at Mersing. What is questionable is whether these units will reach Mersing before the Japanese launch a ground attack sufficient to force 22 Australian Brigade out of Mersing.
In any event, plans are to hold Johore Bahru as long as possible until Allied forces are pushed back onto Singapore.
The Dutch 2E bomber force transferred to Palembang failed to launch a ground attack air strike on Japanese LCU’s at Mersing.
Current situation map of Malaya and latest ground combat AAR’s at Mersing follow. From information shown in the AAR’s below, it appears that Japanese LCU’s in Mersing have almost completely disembarked from their ships. Reinforcing an Allied defense of Mersing could already be too late. Several entries in the 12/20 Sigint report indicate Pillager is sending additional Jap ground units by sea into Mersing.
