After cancelling a few games in 1968 due to financial difficulty, the Charter Oaks announced they were ceasing operations in March 1968. The team cited losses of approximately $250,000.[2] The Atlantic Coast Football League immediately established the Hartford Knights to replace the Charter Oaks in the market, and by at least one player's account (that of eventual Pro Bowl fullback Marv Hubbard), the Knights were still known as the Charter Oaks for at least their first season.[3] The Knights would play for the next six seasons, winning the ACFL title in 1968, appearing in but losing the title games every year from 1969 to 1971, and winning the Seaboard Football League in 1972.[4]
