George Langford in the Revolutionary War

I thought I should take a minute to complete some details about George Langford's service in the Revolutionary War. I have a membership in Fold3 which provides access to most American military records online. I quickly had George's files.
George Langford was the grandfather of Oscar Langford. He was born in 1755 and signed up on October 16, 1779. He joined Captain Joseph Clap's Company of the Third Regiment of Massachusetts Bay Militia commanded by Colonel Israel Chapin. Their unit contained a drummer and fifer and a surgeon, four sergeants, four corporals, 39 privates and a few other staff.
 From Wikipedia:
The 3rd Massachusetts Regiment also known as the 24th Continental Regiment, Heath's Regiment, and Greaton's Regiment, was raised on April 23, 1775, under Colonel William Heath outside of Boston, Massachusetts. When Heath was promoted to brigadier general in June 1775 the regiment came under the command of Colonel John Greaton. The regiment would see action at the Battle of Bunker Hill, Battle of Trois-Rivieres, Battle of Valcour Island and the Battle of Saratoga.The regiment was disbanded, on November 3, 1783, at West Point, New York. Lineage carried on by the U. S. 104th Infantry Regiment.
From family history we understand that he would tell his grandchildren about the difficulties he encountered at Valley Forge. There is no doubt that he was at Bunker Hill as his rifle was shot out of his hand, for which he made a claim.
