Lenora,
My mother taught me not to answer a question with a question, so I hope you will not think me rude to ask to which battle do you refer and where is Chalk Creek? It may help if we knew who commanded on each side of this fracus and when it took place. I am not a local (as you may detect) and I cannot locate Chalk Creek on the 1:100,000 scale government charts I have.
I cannot help with a court martial for Captain Leeper, but I imagine someone else can do that for you.
