An officer of the Royal Marines reported that no flags were used by the rebels. John Trumbull, known for his historic detail, and who witnessed the battle through a spyglass, used a red flag with a pine tree in his painting The Death of General Warren at the Battle of Bunker Hill. Another flag which commonly represents the battle has a plain blue flag and a canton quartered with cross of St. George (the symbol of England) and a tree in a quarter of the canton. Although possibly inspired by the Blue Ensign of the Royal Navy, the blue field is said to have been due to an error in a wood engraving, causing confusion with painters. However, Benson John Lossing writes in Field Book of the Revolution that he interviewed the daughter of a Bunker Hill veteran who told her that he hoisted a blue flag on Breed's Hill prior to the battle. Regardless of its authenticity, the blue variation of the New England flag has become a symbol of the Battle of Bunker Hill, and was featured on a 1968 US Postage Stamp.
