Tryon died at his home in London on 27 January 1788 and was buried at St Mary's Church, Twickenham, Middlesex, England.

Tryon's policies during the American Revolution were described as savagely brutal by persons on both sides of the conflict.
Although he has been described as a tactful and competent administrator who improved the colonial postal service, he became unpopular first because he obeyed the instructions of his superiors prior to the war and then disobeyed them during the war by being overly harsh in his conduct of the war in the neutral ground in New York.

For example, historian Thomas B. Allen notes on p. 202 of his book Tories that 'Tryon's desolation warfare shocked many British officers and outraged Patriots.'
According to Allen, 'Joseph Galloway, a leading Tory, charged that marauding and even rape was officially tolerated by the British and the Loyalists.
Galloway said that "indiscriminate and excessive plunder" was witnessed by "thousands within the British lines."
In a "solemn inquiry," backed by affidavits, he said, "it appears, that no less than twenty-three [rapes] were committed in one neighborhood in New Jersey; some of them on married women, in presence of their helpless husbands, and others on daughters, while the unhappy parents, with unavailing tears and cries, could only deplore the savage brutality."
Similarly, in New York City, citizens and officers accused Hessians, Redcoats, and Loyalists of robbing houses, raping women, and murdering civilians.'
