Cornish Pirates boss Ian Davies says his side came across a 'ruthless' Bristol team as they lost 40-10 to the Championship leaders at the Mennaye.
The Pirates led 10-7 at half time thanks to Joe Atkinson's try and a Kieran Hallett penalty before Bristol scored five unanswered tries.
"It was a comprehensive defeat," Davies told BBC Radio Cornwall.
"If you spend most of the time inside your 22 the pressure's going to build, they took their tries very well."
The loss leaves the Pirates second-from-bottom of the Championship, one point above bottom side Ealing.
It was the first time that last season's beaten play-off finalists have won at the Mennaye since May 2010, a run of six successive defeats.

"They came down here last year, scored six tries and lost because they weren't ruthless," added Davies.
"This year they weren't prepared to take their foot off our throats and you saw that.
"I thought our try was a very good team try, but hand on heart did we think we deserved to be in the lead at half time? Probably not with her amount of possession and territory that we had.
"But look down their side at the quality they've got and the Premiership experience they've got.
"You're talking about a side who are looking to go into the Premiership. They should have last year, they missed out, they've got no threat like they had last year in Worcester, there's no-one in the league this year who can put a hand on them."
