Second half goals by Byron Walker and substitute Billy Bennett earned Sevenoaks Town their first Southern Counties East League Premier Division win of the season at The Bourne Stadium on Saturday.
It was a hard earned victory over the Medway new-boys, relegated from the Ryman League last season.
Walker and Bennett were two players facing one of their old clubs - with skipper Corey Holder and Greg Benbow completing the quartet, while Chats goalkeeper Ryan Nicholls made a quick return to Oaks, having made three appearances for the club last season.
John Wilfort and Julian Leigh were again in charge with boss Micky Collins serving the second of his three match stadium ban.
0aks made two changes from the side that started the 3-1 FA Cup win against Broadbridge Heath - Paul Springett and Andy Irvine earning starts ahead of absent Joe Bingham and Brett Ince who was on the bench.
Walker saw a fourth minute goal ruled out for offside by referee Hossain Tavakkoli after a lengthy chat with assistant Graham Smart.
Four minutes later the London official produced his yellow card - the first of nine in the game - when Chats striker Ricky Gundry went in heavily on Holder.
Walker missed out again after 20 minutes, scuffing his final shot, after Jack Miles' cross was headed on. Harrison Carnegie then saw his effort saved, then Greg Benbow saw his effort deflected for a corner.
Town went close again six minutes before half-time, Chris Edwards and Carnegie combining well on the left before Miles headed over at the near post.
Chatham went close to grabbing the lead early in the second half, Jordan Gallagher firing wide as the ball dropped to him at the far post.
A minute later Oaks were in front. Edwards and Tom Youngs started the move, before the ball was played into the path of Walker to fire home.
Justin Ascheri fired over at the other end, before Walker headed Edwards' cross over the bar. Bennett then saw Nicholls push away his effort, with Craig Holloway blocking his effort. The keeper pushed away another on target effort, before Town made sure of the points two minutes into stoppage-time.
Youngs was involved in the second two minutes into stoppage time playing in Bennett who did the rest.
New signing Darren Marsden and Ince also came off the bench in the second half.
Both teams held a minute's silence before the game, following the death of former Club Chairman Tony Smart last week. We send our condolences to Sue and the rest of the family following their sad loss.
