Anderson latched onto a loose ball with seconds remaining, to grab what could prove to be a vital away point for the Spireites, and the manger hopes the players can carry that momentum into tomorrow’s fixture against the Shakers.
"There is no greater thing for team spirit than getting results with your team mates when it looked like time was running out” said Caldwell.
"The belief never ran out, the desire to get something from the game-from the bench, the players on the pitch and from the fans in that corner was there until the last minute, and we got our reward. That can give you real momentum and real belief.”
"I said after the game, when you draw games they only become good draws if you win the game after, while it was a massive point we have to now capitalise on that.”
On the injury front, the manager revealed Ched Evans and Jon Nolan will miss tomorrow’s game but Ryan Fulton has recovered from illness and is available for selection.
He said: “Ched’s still injured, he’s getting further scans. So far there has been nothing major that's worrying. He’s getting a last scan today, should that be clear, hopefully we’ll see him very soon.
“Ryan’s back training from his illness so he’s back available. Jon Nolan, with his hamstring will miss Saturday and probably a few games after that but everybody else is fine.”
The Spireites will face up against a Bury side under new management. With the Greater Manchester side announcing on Wednesday that former Kilmarnock manager Lee Clark will take the reigns, and Caldwell admitted it’s made preparation for the game difficult.
He explained: "I've had it before in my management career where a manager comes in and you have to look further in terms of the different types of formations and styles of play that he plays. You have to be aware that different things might happen.
“The players know the different scenarios that can come up and are prepared to play against whatever Bury throw at us. They are a team that play with energy. They play with real passion and their strikers are threat.
“I know we are in for a difficult game. We have to match their physicality and we have to match their enthusiasm for the game.
“Then we have to play our own game and control it, the way we have been and add that finishing touch, that creativity in the final third to make sure we get the win.”
The Scot is well aware of the importance of the game but insists he has full confidence in his players to get the win and put together a run of results.
"Every game is big. I treat every game the same whether we are playing a team right next to us or a team at the top of the league,” he said.
"I've said to the players that I believe they can win any game of football, against any team in this league so it doesn't really matter who we are playing against. We just see it as three points and we want to try and get that and move on and gain momentum from Tuesday.
"I'm a big believer in putting unbeaten runs together because that breeds confidence, we know that Gillingham was a big night for us in terms of momentum but now we have to capitalise.”
The boss also thinks that the Spireites faithful could have a vital part to play in tomorrow’s game.
"They've been fantastic since I came to the club and we need them in big numbers and big voice on Saturday, from the start of the game right until the very end,” he concluded.
