Joe Dunne started his tenure as Colchester United manager with victory over Hartlepool.
But Dunne's first game in charge got off to the worst possible start when Craig Lynch pounced on an error by Craig Eastmond to put Pools ahead after just five minutes.
Gavin Massey fired past Scott Flinders to draw the U's level.
Jabo Ibehre coolly slotted the hosts ahead and the forward made it 3-1 when he stabbed home from close range.
Colchester United manager Joe Dunne told BBC Essex:
"It's a start. We should enjoy it because we've not had a win this season, but understand it's only a start.
"After the goal [for Hartlepool] it was starting to gather momentum. After about 10-12 minutes it was starting to happen.
"When it did I thought we looked really good and I thought we could have scored more.
"Even when we got the third I thought we'd get some more but you never know so you have to stay focused. The players did that even when it was a bit scrappy at times."
Hartlepool United head coach Neale Cooper told BBC Tees:
"The personnel are not doing it, the last few games it's killing us, every attack was a worry.
"We sit and talk to the players during the week, we try to work on things, but every time they attacked there were problems. I wouldn't like to play behind the back four.
"I feel sorry for Scott Flinders [goalkeeper]. It was error, another goal, error, another goal. The second goal was absolutely shocking, we gifted them two, no three, goals."
