While it's true that I lost a number of my forces unnecessarily attacking Marshall turn 1, I think the larger strategic blunder on my part was that I planned my strategy around war breaking out turn 1. When that didn't happen I fell into a cycle of building up my forces to compensate for the lack of fighting weather and choosing not to attack because of the unfavorable weather in the later turns. The end result was a compromise army, that was basically incapable of doing anything for the middle three turns without getting caught in the open waiting for a counter. Holding back obviously didn't go much better.
