England was routed by West Indies fast bowler Kemar Roach as the tourists were bowled out for 77 on Thursday, with 18 wickets falling on day two of a remarkable first test.
West Indies finished the day 339 runs ahead on 127-6 in its second innings after Ben Stokes and Moeen Ali led a spirited but seemingly hopeless fightback with the ball.
It was a third batting collapse in the West Indies for England, which was skittled for 46 in Trinidad in 1994 and 51 in Jamaica a decade ago and now tumbled to the lowest ever test total at the storied Kensington Oval.
Roach did most of the damage, taking five wickets for 17 runs as he wiped out Rory Burns, Jonny Bairstow, Stokes, Jos Buttler and Moeen in a glorious spell after lunch. All of his wickets were concentrated in the space of 27 deliveries.
England had emerged for the afternoon on 30-1, with Keaton Jennings the man to go after spraying Jason Holder to gully. Jennings' continued struggles against seam are a lingering concern, but his 17 runs ended up being the top score of the innings.
Burns added only two before he pushed forward at his first ball after the restart, allowing it to skim off the bat and into off stump, and Bairstow was next to succumb to one that spat off a length, grazed his elbow and dislodged the bails.
Holder chipped in from the other end to remove rival captain Joe Root, following up 11 successive dots with a plumb lbw.
Roach soon reclaimed the spotlight, revving up to strike with consecutive balls. Stokes was given lbw on the back foot, unsuccessfully reviewing a marginal decision, while Moeen's shot was a curious flap top-edged to fine leg.
Roach's fifth was probably the best, Jos Buttler forced on to the back foot by a brutish steepler and feathering behind.
His colleagues then finished the job, with Shannon Gabriel bouncing out Sam Curran and Alzarri Joseph teasing edges from Ben Foakes and Adil Rashid.
Holder opted not to send the tourists back in despite a lead of 212, which was built on by a 52-run opening stand between John Campbell and Kraigg Brathwaite.
But the West Indies managed a wobble of their own, losing five for nine once Moeen picked off Brathwaite lbw.
