Danny Webb praised the character of the players after they came from behind to win 2-1 against Dagenham & Redbridge, with both goals scored by Kabongo Tshimanga from the penalty spot.
Captain William Wright almost sent Dagenham into the lead on the half-hour mark, hitting the post from a free-kick around 20 yards out.
Dagenham took the lead 35 minutes in through Josh Walker when he ran at the defence and drilled the ball into the bottom left corner.
The Spireites won a penalty towards the end of the half when Jeff King was brought down in the box. Top scorer Tshimanga (44) stepped up and hit the ball straight down the middle.
Once again, Walker was causing problems for the Spireites, getting a shot away inside the box, but Scott Loach kept it out, keeping the scores level going into half time.
Jak McCourt went close for the Spireites early in the second half with a low driven shot from range which went narrowly wide.
Chesterfield were awarded their second penalty of the game when King was brought down once again. Tshimanga (62) stepped up and slotted the ball into the bottom right corner for his second of the game.
King almost doubled the Spireites’ lead with a free-kick from around 25 yards out that went just wide.
Liam Mandeville cut inside from the left-hand side trying to get a shot away, but his attempt was blocked.
The Spireites kept up good pressure on Dagenham after taking the lead and defended well when needed.
Webb said: “I thought the performance showed all of the things that I asked of them.
“We all want promotion, we all want to win games at home, we want to get people off their seats.
“I thought the goal was avoidable but after that we didn’t crumble, we showed some character.
“And fair play to the fans because they didn’t show any sign of turning on the players, so that was much appreciated because they never do. They just support, support, support.
“They were fantastic, the boys – second half especially – and I think we really turned it on a bit with the way we played.
“Towards the end the nervousness wasn’t as much as it has been in the past when there’s a one-goal lead. We did sit so deep although we could still be a bit higher. But we spoke about it in there, the boys have taken it on board and I’m just glad that they can enjoy their weekend.”
