It was a quite astonishing day at Lord's, the home of cricket.
Ed Joyce, who played for both Ireland and the hosts, rang the ceremonial five-minute bell before play, pealing doom for an England side that won the toss and decided to bat on day one of the first ever Test between the two countries.
What followed was to say the least unexpected as Ireland skittled England out before lunch for just 85 runs in less than 24 overs, England's shortest ever first innings in a home test match, and at the end of the day's play led by 122 runs.
Ireland claimed the first wicket in only the third over when England debutant Jason Roy was caught by Paul Stirling at first slip off the bowling of Tim Murtagh.
Mark Adair, on debut, had troubled Joe Denly from the pavilion end, and he finally trapped Denly plumb in front in the 10th over, out LBW for 23 with England 36 for 2. That became 36 for 3 when Murtagh took his second wicket as opener Rory Burns was caught behind by Gary Wilson for just 6.
England captain Joe Root became Adair’s second victim with the score on 42 when, on review, Root was given out for 2, absolutely plumb in front of his stumps and England fell to 42 for 4.
Incredibly,Jonny Bairstow was clean bowled for 0 by Murtagh and Chris Woakes was LBW, also to Murtagh, and England were now 42-6.
Murtagh, a Middlesex player who plays his county cricket at Lord's, then took his fifth wicket as Moeen Ali was caught behind and Murtagh had 5 for 11 off his 8 overs at that point.
Boyd Rankin, a former England test player, took a wicket in his first over, as Wilson brilliantly caught Stuart Broad for just three diving away to his right and England were 58 for 8
Rankin dismissed Sam Curran for 18 caught at short leg by James McCollum, 67 for 9 in only the 20th over and then Adair bowled Ollie Stone for 18 and, amazingly, England were all out for just 85 runs.
Ireland opening pair of William Porterfield and James McCollum put on 32 for the first wicket in their first innings before the Irish captain perished on 14 in Curran’s first over
McCollum made 19 before he played on to Curran and Ireland were 45 for 2.
That brought Paul Stirling to the crease on his home county ground and having being dropped at slip by Root off the bowling of Stuart Broad when he was on 17, Broad finally trapped him in front for 36 with Ireland 132-3.
Andy Balbirnie made a fine 55, his half century off just 55 deliveries before he was bowled by Ollie Stone before Gary Wilson and Stuart Thompson quickly followed - both for nought - and Mark Adaair dragged on for 3, Ireland falling to 149 for 7.
Andy McBrine and Kevin O’Brien added 25 important runs for the 8th wicket and Tim Murtagh slapped a quick 16 to help take Ireland into a three-figure lead.
England’s nightwatchman Jack Leach and opener Rory Burns had to survive one Murtagh over before the close of play as they ended the day on nought for naught at the beginning of their second innings
Day one was astonishing, day two could be equally as dramatic in this topsy-turvy one off Test match.
