• Our secondary crossing forces making their own shock attack shows that our primary crossing forces did not have adequate AV to have a proper bridgehead. Our 2 units destroyed were USA combat engineer regiments.
• My attempt at combining the casualty stats at Singapore.
Totals from both battles:
Japanese ground losses:
15496 casualties reported
Squads: 205 destroyed, 1274 disabled
Non Combat: 21 destroyed, 188 disabled

• The tactical air support at Johore Bharu will make strikes tomorrow and the light cruisers will bombard tonight. I will consider it very good luck to avert a further disaster. The battleships are on the way back, and the RN heavy cruisers will pull back from Cam Ranh Bay where they were standing by to support those operations. Some USMC MB and AB which just shipped to Mindanao is moving to Johore Bharu to add their support.
• Consider the situation if the Empire knew that we had more units coming which would also be required to break themselves in a shock attack, and the Empire accordingly had waited until the following day to launch the counterattack.
• Disruption is high in the artillery units, devastatingly high in all other units.
• 1,348 AV at Singapore. Another Bde with 123 AV arrives on the scene of disaster tomorrow. We will find out if we now have a proper lodgment. My guess is the high casualties the Empire's forces suffered in their attack on the bridgehead has saved the day by allowing us the needed ratio.
