The Tornado That Saved Washington
'On the night of August 24, 1814, British troops led by Rear Admiral Sir George Cockburn marched on Washington, D.C. and set fire to most of the city. Dolley Madison famously saved the Gilbert Stuart portrait of George Washington and a copy of the Declaration of Independence before she fled to nearby Georgetown. The British didn't stay long, though; their occupation lasted just 26 hours. What happened?
Current Washingtonians will recognize this scenario, as we've had a wild summer of heavy heat and damaging storms. But August 25, 1814 was even worse. The day of the invasion had been hot, 100 degrees. With much of the city aflame the next day, British soldiers kept moving through, lighting more fires. They didn't notice the darkening skies, the thunder and lightning. City residents knew a bad storm was on its way and quickly took shelter. The British, though, had no idea how bad a D.C. storm could get.
The clouds began to swirl and the winds kicked up. A tornado formed in the center of the city and headed straight for the British on Capitol Hill. The twister ripped buildings from their foundations and trees up by the roots. British cannons were tossed around by the winds. Several British troops were killed by falling structures and flying debris.
The rain continued for two hours, dousing the flames. The British decided it was time to leave. Local meteorologists later wrote in their book Washington Weather:. . .
