Admiral Edward Vernon was best known for his 21 November 1739 capture of the poorly defended town of Porto Bello, Panama, from the Spanish with just six ships. This 1739 triumph was followed by an infamous failure at Cartagena, Colombia, in 1741. It was during this ill-fated campaign that George Washington’s brother Lawrence served on Vernon's flagship. Admiral Vernon--who was called “Old Grog" for his penchant for wearing grogham coats--is perhaps best known for the result of his effort to reduce drunkenness by watering down his sailors’ daily rum ration. As lemon or lime juices were added to offset the water’s brackish taste, Vitamin C led to much-reduced rates of scurvy and other diseases in Vernon's fleet. The drink became known as "Grog.”
