John Askey’s side were beaten with Tom Naylor's 95th minute goal at the SMH Group Stadium as the Spireites came from 2-0 down.
Emmanuel Dieseruvwe and Anthony Mancini gave the travelling 1,030 Hartlepool supporters plenty to cheer in the early exchanges as Pools raced into a commanding lead.
But despite the defeat, it was another excellent backing from Pools fans.
