Sorry. Can't post either right now, or rather, can post but may not be able to answer.
Anybody else looking at the photographs posted now and thinking... is it possible?
The USA also recognizes November 11th as Armistice Day, now called Veterans' Day -- a day to honor those who fought in one of the Great World Wars. Memorial Day is a day to remember any veterans who have died. At the service I attended there were names called out who had died in the Civil War and in the Revolutionary War.
