This is an excellent, well animated synopsis of Yorktown and the events that led up to it:

The live action footage was taken from ‘The Battle of the Hook’ reenactment which I participated in. It was my first reenactment, and as noted in this post, I spent the majority of the first battle on my back. But alas, not all was lost! Seems as if the camera guy noticed my fabulous acting skills and incorporated me into the series at the 37 second mark:

45 solid minuets of acting. Will submit my nomination for “Best Historical Reenactment of a Dead Guy” category.
I highly recommend you check out the entire series, which is divided into small 2-3 minute chunks. The production, design and graphics are top notch. Hats off to the visual team for their work.
Wow, great acting!! 4WIW, same thing happened to me yesterday at a Battle of the (Hudson) Highlands reenactment. I thought, to my great satisfaction, that while all around me had fallen on the last enemy fusillade, I was in turn going to blow away a line of the enemy. Unfortunately, I then realized after priming my pan that my cartridge had little powder left for the barrel, the remaining grains having somehow fallen out. With time running out I reached for another cartridge, but the now reloaded enemy’s next volley was concentrated on me and down I went to strike a pose similar to yours! “C’est la vie,” as Lafayette would have said! : )
Thanks for sharing. Now I know I am not the only one! Thanks Bill.
