Robbie Simpson`s firm six-yard header settled the game with 11 minutes remaining.
"I thought we were magnificent and I really cannot praise the players enough, every single one of them," said Forster.
"We started the game very brightly but lost a bit of momentum and they had a go at us. But we regained that momentum very quickly and after that I thought we dominated the game.
"We got our wide players on the ball well and the only disappointment from my point of view is that we didn't score a second goal because we had the possession to do that."
Forster added: "I thought, with the quality Sam (Saunders) has got, that he could have placed the chance that dropped to him just before we scored but he struck it over. His cross for the goal atoned for that though."
