In a tight match where the lead swapped several times in blustery conditions, Bath looked to have the wrapped up the game with a fine second half performance during which Chris Malone landed two penalties and Duncan Bell and the outstanding Lee Mears had tries disallowed.
Gloucester's late rally was a bitter blow, but with Olly Barkley withdrawing on the eve of the match with a calf strain and Andrew Higgins forced out after the warm-up, John Connolly acknowledged that his side had played with great spirit.
"I thought that we played some reasonable rugby at times," he explained. "We have got a problem with injuries, but young Tom Cheesman and Ryan Davis did particularly well today against a very good Gloucester side. They are going to mature into outstanding footballers."
