Question: How old was John O'Mahony when he led the 1998 championship? Passage 1:In 1895, the British government authorized Kitchener to launch a campaign to reconquer Sudan. Britain provided men and matériel while Egypt financed the expedition. The Anglo-Egyptian Nile Expeditionary Force included 25,800 men, 8,600 of whom were British. The remainder were troops belonging to Egyptian units that included six battalions recruited in southern Sudan. An armed river flotilla escorted the force, which also had artillery support. In preparation for the attack, the British established an army headquarters at the former rail head Wadi Halfa and extended and reinforced the perimeter defenses around Sawakin. In March 1896, the campaign started as the Dongola Expedition. Despite taking the time to reconstruct Ishma‘il Pasha's former gauge railway south along the east bank of the Nile, Kitchener captured the former capital of Nubia by September. The next year, the British then constructed a new rail line directly across the desert from Wadi Halfa to Abu Hamad, which they captured in the Battle of Abu Hamed on 7 August 1897. (The gauge, hastily adopted to make use of available rolling stock, meant supplies from the Egyptian network required transshipment via steamer from Asyut to Wadi Halfa. The Sudanese system retains the incompatible gauge to this day.) Anglo-Egyptian units fought a sharp action at Abu Hamad, but there was little other significant resistance until Kitchener reached Atbarah and defeated the Ansar. After this engagement, Kitchener's soldiers marched and sailed toward Omdurman, where the Khalifa made his last stand.
 Passage 2:In the 1998 championship, led by Mayo-born manager John O'Mahony, Galway won their first round encounter with Mayo, before overcoming Leitrim by 1-16 to 0-05 in the semi-final. The first final ended as a draw, 11 points apiece with Roscommon, but Galway won the replay in Hyde Park. In the semis, Galway came up against Ulster champions Derry, and won by 0-16 to 1-09. In the final the team faced a Kildare team that had just beaten the previous year's champions, Kerry, and were coached by 8 time All-Ireland winning manager Mick O'Dwyer. Galway went into the final as underdogs, but outstanding performances from Ja Fallon and Michael Donnellan in that match, along with a superbly taken goal from a young Padraig Joyce, helped Galway overcome the Lilywhites by 1-14 to 1-10. Captain Ray Silke lifted the Sam Maguire, and Galway became the first Connacht team in 32 years to win an All-Ireland title.
