Neil Crowe admitted he was “gutted” after seeing his side defeated in the Evo-Stik League Division One play-off final.
Bamber Bridge were beaten 3-2 in extra-time against Ramsbottom United.
Brig twice fought back from being a goal down but The Rams grabbed a precious third goal to seal a victory.
A huge 1,206 fans turned out in force to cheer on the team.
Crowe said: “I’m not going to lie, I’m absolutely gutted.
“I said to the lads when we equalised for a second time in the final minute, you have been given a chance and we need to take it.
“But unfortunately we didn’t.
“The support was excellent on the day and hopefully some of the fans return next year.
“That support means a lot to a club like Bamber Bridge so those few extra fans will mean a lot for us next year.”
Despite having the better of the first half, Brig fell away and struggled to contain the pace Rammy played at.
And Crowe admitted the visitors were the better side.
He added: “Ramsbottom did have a lot of possession but they didn’t do much with it in truth.
“But we struggled to get our passing game going in the second half and we didn’t get Ally Waddecarr involved as much as we would have like to.
“But every credit to my lads we kept going right until the end and I’m more gutted for them losing the final.”
Midfielder Lennie Reid announced his retirement after Saturday’s play-off final defeat and Crowe hailed the tricky midfielder.
He said: “It came a bit of a shock to us all.
“I’d spoken to the lads and said there is nothing we could do now.
“Then Lennie stood up gave a bit of a speech and said he was retiring.
“I’m disappointed he’s retired and he really is a true gent – he’s easy to manage and he gives you everything when he plays for you.”
