You got to be...
Fucking KIDDING ME!
Yes, this man, born in Philidelphia, SOMEHOW served 7 years in the Portuguese army, did every campaign in the Peninsular (That's what it says - every) and then was a Korporaal in the 7de Bataljon van Linie at Quatre-bras and Waterloo.
I've seen Danes, Germans, Scots, Czechs, Prussians and even French in the NL army, but this is the first time I found an American. Thought it would be worth sharing.
Also note how he's 1,70 cm, while most guys were around 1,55. And the fact he's only 22 during the battles, which would meant he joined the Portuguese army aged 12-14; I leave it to you to trust or not trust this story.
