Tony Mowbray hailed the "spirit and camaraderie" of his side, as Rovers came from behind to beat Peterborough on Thursday evening.
The Blues trailed at the break following Charlie Mulgrew's own goal, but fought back with goals from Bradley Dack (2) and Danny Graham.
Victory leaves Mowbray's men close to securing promotion to the Championship, and the boss was a happy man after the game.
"I believe in the spirit and camaraderie of my squad, they never know when they're beaten and they showed that tonight," he told iFollow.
"It was a tough first 45 minutes against a very good side who have a lot of pace in the forward areas - they asked questions of us.
"I didn't want to change it, really, because I thought our strikers would score more than their strikers, so it was a bit end-to-end!
"Both sides had chances but we managed to take our opportunities in the second half with the help of our fans, who were fantastic again tonight.
"We got the result we were hoping for."
Asked if his side had produced when it mattered most, Mowbray added: "Yeah, I think so.
"Sometimes that has to happen, and it happens because the lads care about and work for each other. They won't accept defeat.
"It was really impressive to see that second half and the dressing room was a good place to be at the end of the game.
"We have to rest well now and get ready for Tuesday [against Doncaster]."
