It is believed that Flag Day was first celebrated in 1885. The tradition continued somewhat informally for years after that and finally in 1893 the Pennsylvania Society of Colonial Dames of America adopted a resolution requesting that everyone fly the flag on that day, June 14. It was not until 1949 that Truman signed an Act of Congress designating the day as Flag Day. You can read more history here.
Last year on Flag Day I posted a favorite anecdote from the Leo Thorsness book, Surviving Hell: A POW's Journey. I'm going to re-post it because it's a reminder of how much our flag really means:
Thorsness was captured in 1967 during the Vietnam War; his cellmate Mike brought them to tears when he scrounged together items to make a flag;
"Mike scrounged a small piece of red roof tile and laboriously ground it into a powder, which mixed with a bit of water, became a faded red or maroon color to make the flag's stripes. We had gotten a bit of medicine in the last year of our captivity, usually a blue pill of unknown provenance prescribed for afflictions. Mike patiently leached the color out of one of the pills and used it to make a blue square in the upper left of the handkerchief. With a needle made from bamboo wood and thread pulled from our single blanket, he stitched little white stars on this field of blue."
It took Mike a couple of weeks to make that flag, working secretly so the guards would not know, and when he proudly showed it to his cellmates, some of them cried. When the guards found the flag, of course, Mike was tortured as he knew he would be all along.
As for the Army, of course, when the Revolutionary War broke out there was no single national army but rather each state had its own militia. The Continental Congress met in May to solve this problem and created a national army. On June 14, 1775, Congress approved the national army and the next day named George Washington as commander-in-chief of the Continental Army. You can read more about the formation of the Army here.
To honor both the Army and our flag, here is the Army Field Band with The Star Spangled Banner - awesome!
