American ships in New England waters flew a "Liberty Tree" flag in 1775. It shows a green pine tree on a white background, with the words, "An Appeal to Heaven."

The "Grand Union" shown here is also called The "Cambridge Flag." It was flown over Prospect Hill, overlooking Boston, January 1, 1776. In the canton (the square in the corner) are the crosses of Saint Andrew and Saint George, borrowed from the British flag.

The "Betsy Ross" flag. The Flag Resolution did not specify the arrangement of the stars nor the specific proportions of the flag. So many 13-star flags were used, as seen from the next several pictures.

According to some accounts, two famous flags were flown at the Battle of Bennington. One, shown here, is called the Bennington Flag or the Fillmore Flag. The story goes that Nathaniel Fillmore took this flag home from the battlefield, and the flag was passed down through generations of Fillmores, including Millard, and today it can be seen at Vermont's Bennington Museum. Most experts doubt this story and date the flag to about 1820. The other (not pictured) has a green field and a blue canton with 13 gold-painted stars arranged in rows. General John Stark gave his New Hampshire troops a rallying speech that would be the envy of any football coach today. He said, "My men, yonder are the Hessians. They were brought for seven pounds and ten pence a man. Are you worth more? Prove it. Tonight, the American flag floats from yonder hill or Molly Stark sleeps a widow!"

Cowpens Flag. According to some sources, this flag was first used in 1777. It was used by the Third Maryland Regiment. There was no official pattern for how the stars were to be arranged. The flag was carried at the Battle of Cowpens, which took place on January 17, 1781, in South Carolina. The actual flag from that battle hangs in the Maryland State House.

Vermont and Kentucky joined the union in 1791 and 1792. This flag with 15 stars and 15 stripes, was adopted by a Congressional act of 1794. The flag became effective May 1, 1795.

By 1818, the union consisted of 20 states. A Congressional act mandated that the number of stripes be fixed at 13 and that one new star was to be added for each new state, the July 4 following its admission. However, nothing was written about what arrangement the stars should be in. This and the following two flags were all used simultaneously.
