What was Charles Cornwallis's evidence?

Charles Cornwallis's evidence primarily consists of military reports, battlefield accounts, and correspondence that documented his strategies and decisions during the American Revolutionary War. His letters to British officials provided insights into his perceptions of the American forces and the challenges he faced, particularly during the Siege of Yorktown. Additionally, the outcomes of key battles under his command, including the surrender at Yorktown in 1781, serve as critical evidence of his military leadership and the eventual failure of British efforts in the colonies.
