Colchester ended their four-match losing run with a narrow 1-0 win over another out-of-form side, Oldham.
Ashley Vincent's second-half strike gave the Us victory in front of the lowest-ever league crowd at the Weston Homes Community Stadium.
Colchester went close in the 13th minute through centre-back Nathan Clarke, who chested Brian Wilson's corner onto the crossbar and over.
But Oldham had their chances too, with Reuben Reid and Cedric Evina both shooting just wide and Us goalkeeper Ben Williams making good saves to deny both Kieran Lee and Ritchie Jones in quick succession.
But Colchester took the lead seven minutes after half-time when Vincent latched onto David Mooney's pass and calmly fired low past Dean Brill from 15 yards.
Williams parried away Dale Stephens' free-kick late on as the Us held on for victory.
