Christmas day brings a nice gift for the garrison at Sabang. After watching their enemy reinforced, no action occurred for the next few days. Both sides dug in and organized, and waited. Today, they woke to the sound of big guns firing, only this time, the shells landed on the Japanese positions. A surface force led by BC Repulse, with the heavy cruisers Frobisher, Hawkins, and Devonshire fired at the 21st division, 16th Guards regiment and 42nd Infantry regiment. Few casualties were confirmed but the morale boost for the allies was significant. The allies followed up with a deliberate attack that crashed against enemy defenses. 470 allied casualties versus 110 on the Japanese side.
December 26th
The allies repeat their deliberate attack again on the Japanese forces at Sabang. This time, they are better organized or perhaps the Japanese are simply more exhausted; despite 1:2 odds, the allies score 1030 casualties at a cost of 640.

Appear at places to which he must hasten; move swiftly where he does not expect you.
