Jordan Rhodes scored twice as Huddersfield came from 2-1 down to beat Colchester.
Rhodes swept the Terriers in front but Colchester hit back through Kayode Odejayi's 12-yard shot and a powerful Michail Antonio header.
A stunning long-range strike from Rhodes levelled the match at 2-2 before Lee Novak lobbed Mark Cousins to win it for Lee Clark's side.
The win extends Huddersfield's unbeaten run to 29 League One games.
VIEWS FROM THE DRESSING ROOM
Huddersfield Town manager Lee Clark told BBC Radio Leeds:
"What the players did was just get rid of the anxiety and the tension that they had at half-time and they just played with freedom. I told them that before, at half time I said that little bit of tension you've got is draining you physically and mentally so just dismiss it.
"That's the standard bearer really from us of what i'm expecting from us for the rest of the season. Between the players and the fans they produced the result.
"Jordan Rhodes has scored two terrific goals today, and Lee Novak is on a terrific run. I threw down the gauntlet to him and all the strikers pre-season and Lee is certainly delivering."
Colchester United manager John Ward told BBC Essex:
"They're a big team, with massive ambitions about trying to get in the league above us and we've given them a tough game.
"I've not bottled anything up. We said we think we can attack and get at them and it's been an exciting game of football.
"But we are going home empty-handed and that's the disappointment for my team."
