I was playing some G42 on Triplea and something weird happen. I was playing the USSR and everybody else was AI. I declared war on Italy (I think it was turn three) and Germany hasn’t declared war on me. Italy attacked Eastern Poland and occupied it (because I only had one inf there). On Germany’s turn they moved a chunk of their force in Eastern Poland (remember Germany and I are not at war) and on my turn I attacked the territory with a couple inf and my air force and was victorious taking it. However, the German forces stayed there and now it’s been several turns later and Germany and I are still are not at war and the German forces are still there.
So my questions are in a real game (aka on an actual board) are the German forces in Eastern Poland allowed to stay there even though now I own the territory, can they move out, and what happens if either me or Germany declares war on each other? I haven’t gotten to the point where either me or Germany has declare war on each other and will tell you what happens when war is declared. If this is legal, I’m a bit puzzled why there can be 30ish German units in a neutral territory. Thanks.
