The machinations of a cabal led by Governor Arthur, and an effort made to deprive him of his well-deserved pension, necessitated Evans's departure for England to defend his claims.
In this he was only partially successful, for the pension which it was understood was for life, was stopped in 1832.

He returned to Tasmania, and passed the rest of his days at his residence, Warwick Lodge, at the head of Newtown Bay.

He died at the age of seventy-four, and is buried in the old cemetery, Hobart; his second wife, Lucy Parris, rests in the same grave.
Evans was a clever draughtsman, and some of his sketches of the country explored are reproduced in Oxley's journal.

He also published a book entitled History and Description of the Present State of Van Diemen's Land.
It was on Saturday, the 20th of November, 1813, that Evans, in charge of five men, one of whom had been with Blaxland's party, started from the point of forest land on the Nepean known as Emu Island.

He lost no time in following the tracks of the late expedition, leaving the measurement until his return.
