Yeovil Town Ladies were crowned champions of FA WSL 2 after they cruised to a 3-0 win at home to Sheffield.
Lucy Quinn and Annie Heatherson found the target before Nicola Cousins struck late on, as the Glovers capped their historic promotion to the top flight with a commanding display in front of a record 1,483 crowd.
Despite knowing they needed to match Bristol City's result to be sure of the title, Yeovil were showing no signs of nerves and took a deserved lead on 15 minutes when Quinn picked up the ball just outside the box and rifled past Claire Wallhead.
Quinn nearly made it two after a sumptuous back-heel from Kayleigh Green, but the ball just missed the post.
With Bristol racing into a four-goal lead at Oxford by half-time, there was an uneasy feeling around Huish Park as the second half started, but Heatherson put any remaining doubts to bed when she rose to head home Green's cross less than a minute after the restart.
And Cousins put the icing on the cake 10 minutes from time when her cross from the right found its way into the bottom corner to spark wild scenes of celebration.
Yeovil captain Ellie Curson said: “The guys in the crowd today have made our dream come true. They were absolutely incredible, I can’t thank them enough.
“We had a little talk at half-time. We did know the Bristol score, we knew there was a little bit of pressure on our shoulders and we had to go out there and make sure that was ours.
“It’s been a long time coming. It’s been ours since May and no one was taking that off us.
“I’d like to thank everyone, mainly the fans, you could just hear it today. 1,400 people have come out to watch little old Yeovil Town Ladies play.
“It’s incredible for absolutely everyone; the management, players, I’d like to thank everybody.”
