War of Attrition's confirmation and pedigree suggested his potential would blossom when jumping fences over distances, emphasizing stamina. Therefore, his second at the 2004
Punchestown Festival in the Swordlestown Novices Cup Chase the following month, providing compensation for the Arkle disappointment and supplying a more accurate indication of War of Attrition's ability after reported minor setbacks latterly in his novice season.[1]
Victory over the previous season's Cheltenham Gold Cup winner
Lexus Chase at the Leopardstown Christmas meeting provided a good preparatory run before the testing 3+1⁄4 miles of the Cheltenham Gold Cup.[1] Ridden prominently, the combination of good ground and racing beyond three miles for the first time saw War of Attrition travel comfortably with the generous pace during the festival showpiece. Taken to the front three fences from home by jockey, Conor O'Dwyer, Mouse Morris's stable star jumped impeccably and ran on strongly up the Cheltenham hill to win racing's most prestigious chase by 2+1⁄2 lengths from 2005 Grand National hero, Hedgehunter.[1][3] War of Attrition's win gave O'Dwyer a second victory in the Gold Cup ten years after Imperial Call claimed the race and Ireland a Saint Patrick's Day first, second and third with Forget The Past completing the placings along with his compatriots.[1] Another grade-one win followed at the Punchestown Festival in the Guinness Gold Cup for War of Attrition when making all to beat Beef Or Salmon by a comfortable 2+1⁄2 lengths, rounding off a highly successful 2005/06 season and confirming his standing as a high-class staying chaser.[1]
Racing on less favourable soft ground, the following season proved more difficult, yielding only one win before War of Attrition picked up a tendon injury when in the final phases of preparation for an attempt to defend his Cheltenham Gold Cup crown, keeping him off the track for nearly two years. Groundbreaking
stem-cell therapy on the tendon,[4] combined with sympathetic handling by Morris – described as "an artist, distinct from the commercial horse trainer",[5] brought the brown gelding back to a good level of form once recovered. The long absence and the need for him to be raced on softer ground to aid his soundness meant War of Attrition never scaled the heights of past glories but still recorded two more victories over fences during the 2008/09 season and a never-threatening second in the grade-one Lexus Chase behind Exotic Dancer.[1]
The 2009/10 season was earmarked as War of Attrition's last in racing, in which a return to hurdling was implemented in a bid to renew enthusiasm in the veteran after finishing mid-division in the
Punchestown Festival provided a fitting end to War of Attrition's career who, on good ground and racing beyond three miles produced another stirring display under Davy Russell to finish a superb second, 3+1⁄2 lengths behind Planet of Sound with 2008 Cheltenham Gold Cup winner Denman back in fourth.[1][6]
Retirement
Immediately after his final race, owner
euthanized after suffering from colic, on 21 October 2022, at the age of 23.[2]
