Ok, I guess this failed miserably… Can’t shoot me for trying…
Yes, Mario, it was Vice Admiral Horatio Nelson. While not the first time he gave his captains freedom to engaged as they saw fit under his concept, the best example would be prior to the Battle of Trafalgar. Several days before the battle he said to his captains, “Should signals not be understood, or flags obscured, no captain can do very wrong by placing his ship alongside that of the enemy.”
As for the casket. The short story is at the Battle of the Nile, the French flagship, the L’Orient caught fire and exploded. She was a major warship, with tons of gunpowder onboard, and was literally splintered. A large section of her lower mainm’st landed on the deck of Captain Ball’s ship (I blank out on the ship’s name). Captain Ball had a unique personality (and he was one of Nelson’s favorites) which led him to order his carpenter to make the the mast section into a coffin for the Admiral!
