The Battle of Makassar was a sortie by British and Dutch ships from their base in Soreabaja to the port city of Makassar. The Japanese were landing there in great numbers and the allied forces hoped to interrupt or even stop the invasion. The force caught the Japanese totally unprepared and ravaged the landing. It was ultimately unsucessful at stoping the invasion, and for the time the Japanese invasion of the Dutch East Indies was irresistable.
None of the allied cruisers invovled, HMS Cornwall, De Ruyter or Mauritius survived the Dutch East Indies campaign. All were lost to air attack.
