My favorite response to anyone's question about how something happened.
Really, Mom, I was just sittin' here mindin' my own business!
Here's a question back at ya': In the Lost Battalion scenario there's no mention of either turn or place of entry for the four 2nd Cavalry companies. Again, it seems they'd enter on Turn 1 and wherever the owning player desired. On the other hand, varying the time of their arrival might be interesting.
Varying the arrival time does sound interesting and I've put that down on my list of things to try out. Thanks!
