West Indies tumbled to 145-8 in the first test against England and was already facing a heavy defeat by lunch on Day 3 on Saturday.
The West Indian top order had no answer to England's bowlers, just like the West Indian attack struggled against England's batsmen, and the tourists were still 369 runs behind England's first innings of 514-8 declared.
West Indies was also well short of the follow-on target of 315 with two wickets left and even Jermaine Blackwood's resistance on 60 not out wasn't likely to be enough.
James Anderson took 3-23 — and collected a run-out — and Toby Roland-Jones 2-31, as England ripped through West Indies with seven wickets in the session for 101 runs.
Pre-match predictions were that the young and inexperienced West Indies team would struggle in the three-match series in England, but maybe not to the extent of their showing in the first three days of the day-night test at Edgbaston.
West Indies hasn't won a test in England since 2000. Despite having a reasonable record at home against the English, they have been outclassed on tour, losing their last four series in England 4-0, 3-0, 2-0 and 2-0.
England racked up its big score in the series-opener thanks to 243 from opener Alastair Cook and 136 from captain Joe Root.
On day 2, Alastair Cook's 243 carried England to 514-8 declared against the West Indies.
West Indies was 44-1 in reply when rain ended play early and saved the tourists from having to face a full final session under the floodlights at Edgbaston.
West Indies were still a long way behind in the series opener, trailing by 470 runs and already a man down. Kraigg Brathwaite fell for a duck to James Anderson, caught behind by wicketkeeper Jonny Bairstow.
For England, Cook made his third-highest test score, fourth double-century, and passed 11,500 career runs in a performance that underlined the former captain's lasting value to the team.
He batted through England's first innings, sharing partnerships of 248 with skipper Joe Root (136) on Day 1, and 162 with Dawid Malan (65).
England had a mini-collapse in the second session after Malan's departure as the struggling West Indies took five wickets for 65 in the best period of a difficult test so far for the visitors.
That meant England's dangerous allrounders didn't have a major impact on the total as Ben Stokes (10), Bairstow (18), and Moeen Ali (0) all went relatively cheaply. But Cook was magnificent, hitting 33 fours before finally falling lbw to offspinner Roston Chase after a successful video review by the West Indies.
Cook's dismissal brought England's declaration, giving it the chance to bowl at the West Indies top order in the tricky twilight period that often sees wickets fall in day-night tests. Only the rain, which had been threatening for a while, denied England the opportunity and meant an early stumps.
