It's been a 100 days since the cat V dog war started today and two messenger planes have just collided both crashing down on war-torn land, one dog vessel, and one feline. Most letters were damaged irreparably on impact however two vital letters were recovered amidst the burning embers of war, one from the felines and one from the dogs. With either side having the other side's letter... Your the lead cryptologist for the cat's or the dogs, with the power to change the balance of the war drastically with the power of knowledge.

P.S. I used your name as the key, sorry, It's just easier to remember than the standard military key.
