April 16th, 1943
An interesting day. John, as we thought might, elects to bombard Colombo with his ships (although unexpectedly his land forces later in the day don't do any recon bombardment). In the chaos of the night, however, my combat task forces arrive first and prevent any sort of airfield bombardment. Making use of Allied radar capabilities, they manage to surprise the Japanese task forces and inflict a decent amount of damage on three separate combat forces, including heavy damage to and perhaps destruction of a Kongo-class battlecruiser. The battle is not without its costs, however. A lucky shot on CL Adelaide causes her magazine to explode, making her the only casualty of the night's actions. Moreover, both the BB Prince of Wales and BB Revenge take torpedo hits that damaged them, though neither is any immediate danger of sinking.
In total tally, intelligence believes 1 Japanese BC, 2 Japanese CAs, 1 Japanese CL, and 6 Japanese DDs are destroyed in the battle. The damage might be higher or lower (most certainly only 1 Japanese CA sunk).\
Surprisingly, there are no Japanese naval strikes for the day...This could be due to thunderstorms. If so, it's a shame as CAP at Colombo was set to murder anything that came.
