Horndean turned around a three-goal deficit to earn a 3-3 derby draw at Moneyfields.
The Deans looked out of it when Miles Rutherford’s men stormed into a 3-0 lead before the half-hour mark.
But a goal from Tom Chapman before the break proved crucial as the visitors netted another two goals in the second half to grab a point in the Wessex premier division.
Moneyfields were gifted an early lead after a mistake by Jack Stanbridge.
The Deans keeper failed to come out for a high through ball and was left stranded as Steve Hutchings out-jumped Chapman to loop a header into the net.
In the 21st minute Jamie Lacey and Warren Hunt combined to send Rob Evans clear on the overlap, and the full-back gave Stanbridge no chance with his cross-shot.
Six minutes later the keeper was left exposed again as the Horndean defence were caught square, allowing Hunt to set up Bobby Scott at the far post.
Chapman reduced the arrears five minutes before the break and the half ended on a sour note for the hosts as Russell Rackley was carried off with what appeared to be an ankle injury.
Whatever was said in the visiting dressing room at half-time clearly had an effect as Horndean began to reap the rewards for pushing their hosts deeper and depper into their own half.
A period of sustained pressure culminated in Chamal Fenelon forcing the ball into the net through a sea of legs.
And the comeback was complete 10 minutes later when Tom Woodward headed home Louis Castles’ cross.
Deans boss Dave Carter said: ‘It was a poor first-half performance but that late goal before the break gave us the incentive to take the game to Moneyfields in the second half.’
