On the morning of December 19, 1813, Whitney and his family were "driven from their home when the British marched from Lewiston to Tonawanda burning everything in their path.

"[5] They eventually returned in 1814, and began leasing the Eagle tavern, which he later purchased from Augustus Porter and Peter Barton in 1817.

[4] In 1831, he purchased and ran Cataract House (originally built in 1825),[6] which became "the most elegant and popular hotel on the American side.

After a funeral attended by 3,000 people, he was buried with Masonic honors alongside his wife at Oakwood Cemetery in Niagara Falls.
