Belgium went 2-0 up before Bruce McCandless set up a great move with Peter Caruth, the Annadale man finishing off the chance.
Shortly after, club mate Jonny Quigley broke free down the right and crossed McCandless to bring Ireland back to level pegging at 2-2.
The Belgians went ahead once more from a counter-attack but a beautiful diagonal aerial by Chris Pelow (pictured) found Gareth Watkins in the circle, who crossed for Caruth to put away Ireland’s third.
And the Irish hit the front for the only time in the game when Adam Pritchard’s long ball found Caruth, on the right side of the circle. His effort was initially blocked but Gareth Watkns nailed the rebound for a 4-3 half-time lead.
Dave Fitzgerald pulled off a great save from a corner to deny Belgium a leveller in the 42nd minute but a fast break soon after made it 4-4, quickly followed by their fifth from an attack down the left.
But, with five minutes left, Johnny Jackson did the spade work for Caruth and he showed superb composure in the circle and scored a hatrick for 5-5.
