As seen on the [GERMANS-VA] War of 1812 Militia Units message board
...the structure of the Virginia militia during the war. I can only say it is VERY tricky business.
[There were established regiments 1-9]..."And NEW regiments were created numbered 1-9 which could be comprised of units from many different counties.
"The key to that puzzle is knowing the name of the Captain of the unit in which your ancestor served..."
"Fortunately, there is another key to solving that problem, and that is Stuart E. Butler's *A Guide to Virginia Militia Units, War of 1812."
My William Hinds' Captain was Spotswood Henry, son of Patrick Henry.
