Weather affects virtually all outdoor events. The American War for Independence was no exception. Thanks to the late David Ludlum, who assembled vast stores of early American weather information, and others, we learn how the weather played several roles during the Revolutionary War. At key places, including New Jersey in 1776 and Yorktown, VA in 1781, the weather played decisive roles that aided the American cause. In December, 1776, George Washington’s knowledge about the weather helped him elude capture by British General Cornwallis. Several years later, when General Cornwallis surrendered at Yorktown, VA, his hand was forced by a storm that prevented would-be rescue ships from reaching his army. These events, and a variety of other weather-related occurrences are discussed in this journey into the past.

Americans have had more reason than ever to celebrate their freedoms in light of recent events. This AMS meeting, in its colonial setting, encourages us to remember those who risked everything in pursuit of those freedoms.
