Barnsley 3-3 Horsham
Seventh-tier Horsham earned an FA Cup first-round replay with League One side Barnsley after a thrilling six-goal draw at Oakwell.
The Tykes were ahead early on when Max Watters powered in a header from Jamie McCart's corner, but the Hornets levelled when Daniel Ajakaiye played in Shamir Fenelon to finish in style.
Horsham then stunned the hosts when James Hammond hammered home a penalty kick after Corey O'Keeffe brought down Ajakaiye, but Barnsley's Fabio Jalo curled a stunning equaliser into the top corner on the stroke of half-time.
Barnsley went back in front when Mael de Gevigney glanced home O'Keefe's corner and they wasted a host of chances before Tom Richards tapped in for the visitors following a lightning break from Jack Strange.
The two sides will meet again in Sussex on Tuesday, 14 November.
Sheppey United 1-4 Walsall
League Two side Walsall recovered from a goal behind to reach the FA Cup second round with a confident victory at non-league opponents Sheppey United.

Douglas James-Taylor levelled with a clever run and neat finish as Walsall's dominance paid off on a night when they reached the second round for the fifth time in six seasons.
