Kendall spent the fall and winter terms of 1808 teaching in New Ipswich and began attending classes again in March 1809. When the college banned on-campus drinking, students blamed Kendall — who had circulated a petition to have it stopped. He was bullied and nearly assaulted on several occasions, and some students attempted to injure him by dropping heavy roof timbers onto him as he exited a building. Kendall would have left Dartmouth if not for the support of the members of the Gymnasion Adelphon. He later admitted that he learned a valuable lesson from the experience: Never attempt to impose his moral values on others. In July 1809 he joined the Handel Society, and regularly participated in their productions. He again taught in Ipswich from November 1809 to February 1810.
