Lee Noble’s rasping 90th minute free-kick denied Wrexham a fifth win in six outings, as Dartford earned a share of the spoils in a frustrating afternoon for the Reds.
It was a proverbial game of two halves – Wrexham bossed the first 45 minutes and should have built on their 2-1 lead but Tony Burman’s men competed manfully after the break and their gutsy determination was rewarded late on.
Danny Harris swept the visitors into a shock fourth minute lead but Wrexham restored parity through Danny Wright 12 minutes later.
Bishop’s composed 42nd minute chip gave Wrexham a deserved half-time lead before the substitute rifled in that late, great free-kick from 25 yards right at the death.
Despite being full of confidence Wrexham suffered an early blow in the game when Danny Harris latched on to a slide-rule pass on the edge of the 18-yard box. He got ahead of Declan Walker, beat the offside flag and kept a cool head to side-foot the ball past an exposed Joslain Mayebi.
Richard Rose almost sliced the ball into his net from a low Jay Harris shot before Marcus Bettinelli saved from Cieslewicz inside the box.
Wrexham kept the pressure on and it was rewarded when Danny Wright blasted home inside the box after John Hunt’s initial shot was blocked with Dartford’s defenders scattered.
Reds boss Andy Morrell was forced to reshuffle his defence after 21 minutes when Stephen Wright left the field injured. Neil Ashton moved to the centre of defence and Hunt moved to the left-back berth, with Wright’s replacement Glen Little forming part of the midfield.
Wrexham dominated the next 15 minutes but Dartford continued to pose a threat going forward. Declan Walker made a desperate hack away as Harris lurked at the back post before the Darts danger-man pounced on a loose pass from Dean Keates and forced Mayebi into a smart stop.
Three minutes before the break Wrexham took the lead. Bishop took Ashton’s pass into his stride in the box, shrugged off the attentions of his marker before chipping the ball over an already committed and grounded Bettinelli. It was a class finish by the on-loan Bury striker.
The second half exploded into life after a tit-for-tat opening ten minutes. First Keates was denied by a brilliant smothering save from Bettinelli after his initial shot appeared to have been handled in the box. From that, Dartford raced up-field and Jon Wallis forced Mayebi into a low save as his defence creaked.
Keates hacked clear off the line from Darts skipper Elliot Bradbrook as the visitors continued to make a fist of things.
Reds substitute Brett Ormerod had a shot blocked after being played in by Wright before the Darts silenced the home crowd in the final minute. Awarded a free-kick 25 yards from goal just off centre, Noble took a few steps and planted a shot past the wall and beyond the despairing dive of Mayebi.
Wrexham tried to string something together in four minutes of added time but to no avail.
