There, Godfrey was nicknamed "Dutch" and continued to excel academically, demonstrating proficiency in mathematics and engineering. His roommates included Cyrus Comstock (who became a lifelong friend), and Francis Redding Tillou Nicholls of Donaldsonville, Louisiana. When Weitzel was a sophomore, Captain Henry Brewerton was replaced as superintendent by Colonel Robert E. Lee, who took an interest in the top student, but was reassigned himself in March 1855, shortly before Weitzel's class graduated. Nonetheless, Weitzel graduated 2nd out of 34 cadets in the Class of 1855 (his roommate Comstock was first).
