On October 10, the Americans spotted a large house in Yorktown. Believing that Cornwallis might be stationed there, they aimed at it and quickly destroyed it. Cornwallis sank more than a dozen of his ships in the harbor. The French began to fire at the British ships and scored a hit on the British HMS "Charon", which caught fire, and in turn set two or three other ships on fire. Cornwallis received word from Clinton that the British fleet was to depart on October 12, however Cornwallis responded by saying that he would not be able to hold out for long.
