I need some advice on the tactical situation below (march 27, 1942).
I'm playing allies vs AI, I've got 1500 AV in Moulmein and surrounding Moulmein I have 100-200 AV in each hex. The Japanese have some 40k troops, 200 guns and 33 vehicles in Moulmein. This situation started out with the AI wandering into Moulmein with these troops, expecting very little it seemed. I already had 1000 AV or so in place, I diverted some amphibs already on its way to Moulmein to drop behind Japanese lines to cut off supplies, did the same east of Moulmein with troops from Pegu. The Japanese troops in Moulmein already have a (-) modifier because they have low supplies. I've been bombing them daily for about 15 turns with 50 or so medium level bombers from Rangoon and Moulmein. The troops I have in Moulmein do not seem sufficient to wipe them out, already lost loads in deliberate attacks.
My question now is, how to finish them off? I sense big Japanese reinforcements on its way since AI's doing crescendo in DEI, so I don't have months to let this drag on, I need to free these troops to reinforce bits to the north as well. I'm not fully clear on the rules concerning surrounding troops. The way I understand the rules, I could enter Moulmein from all sides with the surrounding troops, thereby being owner of all hexes sides surrounding and in Moulmein, thereby making escape impossible, thus surrender/destruction the only possible outcome. Would this move still cut off Japanese supplies to Moulmein? Or do I need to keep troops surrounding Moulmein to sort that effect?
Perhaps someone can shed some light on this.
