The American flag was flown in battle for the initial time on this day in 1777, in the course of a Revolutionary War skirmish at Cooch’s Bridge, Delaware. Patriot General William Maxwell ordered the “Stars and Stripes” banner raised as a detachment of his infantry and cavalry met an advance guard of British and Hessian troops. The rebels have been defeated and forced to retreat to Brandywine Creek in Pennsylvania, where they joined General George Washington’s major force.
Three months earlier, on June 14, the Continental Congress had adopted a resolution stating that “the flag of the United States be thirteen alternate stripes red and white” and that “the Union be thirteen stars, white in a blue field, representing a new Constellation.” The national flag, which became identified as the Stars and Stripes, was primarily based on the Grand Union flag, a banner carried by the Continental Army in 1776 that also contained 13 red and white stripes. According to legend, Philadelphia seamstress Betsy Ross created the new canton, which consisted of a circle of 13 stars on a blue background, at the request of General George Washington. Historians have been unable to conclusively prove or disprove this legend.
With the entrance of new states into the Union following independence, new stars and stripes were put into represent the brand new additions. In 1818, nonetheless, Congress enacted a law stipulating that the 13 original stripes be restored and that only stars be included with represent new states.
On June 14, 1877, the 1st Flag Day observance occured on the 100th anniversary of the adoption of the flag. As instructed by Congress, the U.S. flag was flown from all public buildings throughout the nation. In the years soon after the very first Flag Day, many states continued to observe the anniversary, and, in 1949, Congress officially designated June 14 as Flag Day, day of observance a national.
