Charlton overcame the setback of having captain Christian Dailly sent off to record a 3-1 win at Leyton Orient.
The Addicks broke the deadlock in a high-tempo derby through Alan McCormack's header but Orient equalised after the break through Scott McGleish before Dailly was red-carded by referee James Linington following a clash with Stephen Dawson.
Charlton survived some fierce Orient pressure, and then in rare breakaway on the hour midfielder Scott Wagstaff was put clear by Lee Martin and finished into the corner. In added time Wagstaff laid on the chance for substitute Chris Solly to tap in a third.
