Years ago I was told that from time to time a wargame situation would occur that actually mirrored real life. I can now attest that this is true. I know how Lincoln felt from just after Antietam until Lee began to move north in June of 1863. Both armies moved out, both went into camp, and both waited for the other side to make the first move. I goaded. I pleaded. I even rplaced commanders. Nothing worked. Both sides stared at each other and claimed the river prevented any activity.
So I'll have to think of something. This isn't quite the campaign I anticipated.
