April 17th ‘99 To Lt. Walbach pg 66 119 New York April 17th 1799 Sir, My object is to see exemplified the elementary evolutions of the Cavalry according to the systems of Prussia, France, and Great Britain in order to compare them with each other and select the best. For this purpose I wished you to instruct in those different evolutions a troop of volunteer horses commanded by Col: Capt. Giles. I have spoken to this officer on the subject and I wish you to see him concert a plan to fulfill the above purpose. You will readily understand that I do not wish to extend your attention to the more complicated movements - but to the simple formation into columns and display in line.
