Joel Lynch was sent off on 12 minutes for an off the ball incident, but Kwesi Appiah gave the ten-men an unlikely lead on the stroke of half-time.
But Tom Conlon, Tom Pett, a George Francomb own goal, and David Amoo fired the Valiants to a seventh win in nine league games.
Photographer Steve Robards was at the game. Here's a selection of his photos.
