A crowd of nearly 500 - all the match programmes sold out at the main turnstile - and a replay against opponents from a leagues above. This was what the FA Cup was all about on "Non League Day" at the Dripping Pan on Saturday.
Oaks thoroughly deserved their second bite of the cherry against another Ryman League Division 1 South side from Sussex, having beaten Horsham 4-2 in the previous round.
Their build-up play in the first half was good against a home side whose manager - ex-Gillingham midfielder Darren Freeman admitted afterwards were nervous and flat.
Joe Bingham headed wide early on - while Lewes hit the bar with Oshane Brown saving the rebound - only for the attack to come to nothing - courtesy of an offside flag.
The game was held up for fully five minutes before home player Dan Perry was carried off with a head injury.
The Lewes striker then needed lengthy treatment from a paramedic - with the club later confirming he had suffered mild concussion. Substitute Charlie Coppola replaced him, and immediately went close with a shot that was pushed away by Brown.
Then early in the second half Oaks defender Corey Holder out-jumped home keeper Chris Winterton, but headed over the bar. Lewes pressed at the other end, Alex Laing miscued in front of goal, and other efforts were snuffed out by Town.
Skipper Chris Edwards saw his effort go wide, before substitute Andy Constable and Bingham went close in the latter stages.
