Invincible Army will stand at Yeomanstown Stud in Naas, Co Kildare next year.
Following a deal agreed with owner Saeed Manana, the son of Invincible Spirit will join Dark Angel, El Kabeilr, Camacho and Gutaifan at the O'Callaghan family's farm.
A high-class performer throughout his career, Invincible Army retires off the back his best season having blitzed his rivals in the Group 2 Duke of York Stakes at York, as well as recording victories in the Group 3 Chipchase Stakes and the Listed Cammidge Stakes.
He also placed in both the Group 1 Flying Five at the Curragh and Group 1 Prix de l’Abbaye at ParisLongchamp.
As a two-year-old Invincible Army won the Group 3 Sirenia Stakes and finished second in the Group 3 Gimcrack Stakes, the Group 2 Mill Reef Stakes and the Group 3 Molecomb Stakes.
At three years, he won the Group 3 Pavilion Stakes before he finished a nose behind Sands Of Mali in the Group 2 Sandy Lane Stakes.
His sire is a known sire of sires and his dam, Rajeem, won a Group 1 winner herself over a mile. He is bred on the same Invincible Spirit/Diktat cross as leading first season sire Cable Bay.
The imposing dark bay proved effective on varying ground conditions on the turf and also on a synthetic surface.
His trainer James Tate said: "Invincible Army was a horse of a lifetime to train. With his remarkable consistency and soundness, he gave us many memorable days on the track and in the winner's enclosure. I look forward to training his progeny in the years to come."
Gay O’Callaghan of Yeomanstown said: "We are delighted to have the oppurtunity to stand Invincible Army. He is an exceptional looking colt, who has shown his tough, honest and consistent attitude throughout his carrer. He is a welcome addition to our roster and I think breeders will be keen to support him."
His stud fee will be announced in the coming weeks.
