Caption: An alleged piece of the elm tree in Cambridge, Massachusetts, where, according to local legend, Washington assumed command of the Continental Army on July 3, 1775, during the Siege of Boston against the British. Sadly, the tree was chopped down in 1923. However, a thousand pieces were salvaged as relics and distributed to interested parties. Father John J. Ryan gifted this piece to Catholic University in 1924.
