Battle of the Clouds

A skirmish took place at the site of the White Horse Tavern shortly after the American defeat at the Battle of Brandywine. A deluge of rain prevented a true battle which may have had dire consequences for the Continental Army. About to be outflanked by British and Hessian forces, the sudden storm enabled the Americans to retreat and resupply their rain-soaked ammunition and prevented the British from crossing the flooded Schuylkill River to move on Philadelphia. Another defeat on the heels of Brandywine could have turned the tide of the war.

At age 19, became the first American and youngest competitor to win the U.S. Open of golf in 1911, and repeated in 1912.

In the years following, the PGA was established, two additional golf majors emerged in the US, and American golfers dominated the US Open and achieved prominence in the world of golf.

Thoma A. Edison High School and the Vietnam War

The number 64 represents the 64 graduates of Philadelphia's Edison High School who fought and died in the Vietnam War. No other school in the nation lost so many. This community’s loss gives perspective to the tragedy of the draft system – these young men had no options for deferment, served their country, and paid the ultimate sacrifice.
