According to the manual, that's not supposed to happen. Of couse, what the manual says and what the game actually does are sometimes two different things. In the epic Peter Vs. Graham AAR on this forum, when Graham overran all of India, no further Allied LCU's appeared there.
However, they were playing Version 3.0. Is it possible that SEAC HQ is still functioning in your game?
One last point--this could be a good thing for the Japanese. Without supplies, the Allied LCU's should be fairly easy to wipe out, thus giving you a rich harvest of victory points.
Civil war? What does that mean? Is there any foreign war? Isn't every war fought between men, between brothers?
