This is all that my book says about it:
The Independence Hurricane of 1775--With
the winds of revolution blowing about in the fledgling 13 colonies, Mother
Nature had a wind that temporarily put a halt to those rebellious thoughts.
A hurricane roared up the East Coast, and triggered one of the early Revolutionary
War skirmishes in the biggest colony of Virginia. It came close to impacting
Georgia and South Carolina on September 2nd before moving ashore over North
Carolina. The storm then picked up steam through Virginia, Maryland, and
Pennsylvania. One of the more notable casualties of the storm was the roof
of the Maryland State House, which was replaced by a wind resistant dome.
