Carmarthen Town 5 Longford Town 1 (Carmarthen win 5-3 on aggregate) The greatest night in Carmarthen Town's history will go down as the most calamitous in Longford's as the Irish side blew their 2-0 first-leg lead in spectacular fashion in Newtown, and it's the Welsh minnows who almost incredibly enter the second round draw in Nyon, Switzerland, at lunchtime today.
An unbelievable second half in which Carmarthen, forced to play 100 miles from their own unsuitable home ground, scored from a fluke and a dubious penalty to get right back into the tie had Longford on the ropes.
The impressive Danny Thomas then put Carmarthen in front in the tie, before a howler from goalkeeper Stephen O'Brien gifted substitute Nathan Cotterall an amazing fifth goal to leave Longford utterly dumbfounded.
On a small pitch, well greased by incessant rain throughout much of the day, Carmarthen did what they had to and took the game to Longford early on, and they got their reward with the lead goal on 15 minutes.
Mark Dodds got a vital flick to Neil Smothers' diagonal ball from the left and Thomas showed his predatory instinct, nipping in behind the defence and this time toe-poking the ball past O'Brien.
It didn't appear to unduly rattle Longford, though, who were level within five minutes, punishing similarly bad defending. Stephen Paisley split the home rearguard to put Andy Myler in on goal with a sublime ball, and Tony Pennock blatantly took the striker down.
Myler sent Pennock the wrong with an emphatic spot kick.
With Carmarthen now needing to score three times more, that appeared to effectively end the tie as a contest.
But it remained intriguing, and in a very open game now, Davy Byrne brought a diving save from Pennock before Longford's goal survived a period of pressure in the minutes before the interval.
A fluke goal did give Carmarthen encouragement, and no little hope, within three minutes of the restart when left-back Gary Lloyd's lobbed ball into the Longford area somehow bounced through to end up in the net.
Pennock made a terrific stop at the feet of Paul Keegan before a dubious decision gave Carmarthen real hope on 64 minutes.
A linesman adjudged Seán Dillon to have pushed Thomas to give away a penalty which Lloyd emphatically drove home.
The jitters had really set in now and Longford crumbled. Kevin Aherne-Evans' flick put Thomas through and he rounded O'Brien to slide the ball home and incredibly put Carmarthen ahead in the tie.
O'Brien's sad night was complete 10 minutes from time. His attempt to dribble past Cotterall some 40 yards out of his goal failed as the substitute robbed the ball off him to give himself a clear run on goal and a simple tap in.
A night to remember then for the tiny Welsh club.
