God what did they teach you in that history class.
It's obviously The Great Oceanic Tiger Battle of 1778. The British dumped tigers into the ocean so they can swim to shore. They did it during a violent hurricane so the tigers can go unnoticed. However, George Washington caught wind of this and said, "I ain't havin' none of that." So he sailed out in nothing but a dingy. As the storm got worse, George began fighting and killing every single tiger he saw. When the storm ended it was thought that he died at sea since only his dingy was discovered. He later appeared on shore that same day with a raft of tiger bodies and a few tigers he sparred. He trained those tigers as assassin's, bread them, and used a tiger army to defeat the British.
