Somerset's last pair held on for 25 minutes before Warwickshire sealed a 10-wicket win in their County Championship clash at Edgbaston.
The home side returned on the final morning needing only a single wicket after Somerset had slumped to 191-9 and a lead of just five runs.
Nick Compton was the last men to fall, narrowly missing out on his century when he was caught on the long boundary for 95 to end the visitors' second innings.
After a battling 81 on day three Compton farmed the strike so efficiently that tail-ender Charl Willoughby faced only seven of the 38 balls bowled in the remainder of his side's innings.
It was Rikki Clarke who took the final wicket, closing out the innings with a return of four for 34 and leavnig Somerset on 208 all out.
With a mere 23 runs to chase Warwickshire openers Varun Chopra and Ian Westwood wasted no time in securing the win, reaching their target in 20 balls.
Warwickshire look certain to do the double over Somerset in the LV County Championship after the visitors ended day three at Edgbaston on 191-9 - meaning a narrow lead of just five.
Facing a deficit of 186 after dismissing the home side for 448, Somerset looked to be going well in their second innings when they reached 86-1.
However the freak departure of Marcus Trescothick, who swept left-arm spinner Chris Metters into Ian Westwood's midriff at short leg having cruised to 55, led to yet another batting collapse.
Nick Compton was the only other batsman to show any sort of resolve, taking nearly five hours to make an unbeaten 81 from 244 deliveries.
However, he received little support from his team-mates; Craig Kieswetter completed a pair for the first time in his first-class carer while Rikki Clarke, bowling at a good pace, took three wickets in the space of 25 balls.
Warwickshire, who had added 50 runs for their final three first-innings wickets in the morning session, then ended Steve Kirby's stubborn resistance late in the day to close in on a comprehensive victory.
Ian Westwood struck his first century of the season as Warwickshire piled up the runs on day two against Somerset at Edgbaston.
The left-handed opener contributed 129 as the Bears reached stumps on 398-7 in their first innings, already a lead of 136.
Westwood, whose 220-ball knock contained 13 fours, extended his opening stand with Varun Chopra to 202 - a record for the county in this fixture and their best in the championship since 2000 - before Somerset finally made the breakthrough shortly after lunch.
Chopra, who scored a double ton against the same opponents at Taunton earlier in the season, was lbw to medium pacer Peter Trego (1-48) for 85.
William Porterfield joined Westwood in a half-century alliance for the second wicket before spinner Murali Kartik (2-85) got rid of Westwood, who was stumped after dancing down the track.
Somerset added four more wickets after tea, including Porterfield bowled by left-arm seamer Charl Willoughby (2-94) for 72, but Warwickshire added a fourth batting bonus point to finish the day in a strong position.
Marcus Trescothick became the first batsman to reach 1,000 first-class runs this summer but his achievement was eclipsed by Boyd Rankin, who claimed 4-41 as Somerset were dismissed for 262 on the opening day against Warwickshire at Edgbaston.
Having opted to bat first, Somerset skipper Trescothick led the way with 69 off 111 balls, his seventh 50-plus score of the season, to leave his side well placed on 125-1.
He needed only 22 to reach 1,000 runs for the fifth consecutive season and he soon got there when he clipped Andy Miller (1-64) for four.
But Trescothick was unsettled by Irishman Rankin, who struck him on the helmet then the right hand before lunch and soon claimed his wicket after the interval as Somerset collapsed.
Lewis Gregory (48) and Peter Trego (56) put on 75 for the sixth wicket but, from 230-5, the Cidermen lost 5-32.
Openers Varun Chopra (33no) and Ian Westwood (48no) powered Warwickshire up to 86-0 in reply by stumps.
