A Lesson in Naval Logistics
On 23 August 1779, the USS Constitution set sail from Boston, loaded with 475 officers and men, 48,600 gallons of water, 74,000 cannon shot, 115,000 pounds of black powder and 79,000 gallons of rum.
Her mission: to destroy and harass English Shipping
On 6 October, she made Jamaica, took on 826 pounds of flour and 688,300 gallons of rum. Three weeks later, Constitution reached the Azores, where she provisioned with 550 pounds of beef and 300 gallons of Portuguese wine.
On 18 November, she set sail for England where her crew captured and scuttled 12 English merchant vessels and took aboard rum.
By this time, Constitution had run out of shot. Nevertheless, she made her way unarmed up the Firth of Clyde for a night raid. Here, her landing party captured a whiskey distillery, transferred 13,000 gallons aboard and headed for home.
On 20 February 1780, the Constitution arrived in Boston with no cannon shot, no food, no powder, no rum, and no whiskey.
She did, however, still carry her crew of 475 officers and men and 18,600 gallons of water. The math is quite enlightening:
Length of cruise: 181 days
Booze consumption: 1.26 gallons per man per day
(this DOES NOT include the unknown quantity of rum captured from the 12 English merchant vessels in November).
Naval historians note that the reenlistment rate from this cruise was 92%.
LOGISTICS LESSON LEARNED:
Don't load up with too much water.
