I have upgraded my computer and with a better monitor what I found was what I thought I saw in person but unable to make out when I first reviewed the footage. That night back in 2007 I kept thinking I could see a dark figure inside the secured courtyard next to the chapel. I am sure there is something there now so I will go ahead and post it. I panned to it twice and even zoomed in at one point. To me it looks like a person in period clothes with a rifle and a tall hat common to the uniforms at the time of the battle.
notice the soldier and also the shudder on the window flapping like crazy with no wind (see trees).
