George Jaggs played for Kangaroo Point-based club Wellington before the war, alongside his elder brother Thomas. Both would enlist for the war, with George signing up in August 1914. By the time Thomas signed up 12 months later, George had been invalided back to Australia.
George was allocated to the 9th Battalion. He was shot in the left thigh during the landing of Gallipoli on 25 April 1915 and arrived at the No. 17 General Hospital in Alexandria on 1 May. The hospital was ill-equipped for the inrush of patients from Gallipoli. It had been sent out from Australia without female nursing staff, while the number of beds was greatly inadequate. The authorities had ill-judged the demands of the oncoming landing. By the time Jaggs arrived, only two local nurses had been employed, while four Australian nurses were borrowed from another unit.
Jaggs left in mid-July at which time the number of nursing staff had greatly increased. The hospital would eventually expand to over 2400 beds. Jaggs arrived at Weymouth Base Depot in England in October, where it appears he stayed until being invalided back to Australia in March 1916.
He arrived home a few days after the first anniversary of the landing and was formally discharged as medically unfit in late May. Jaggs lived periodically with his sister Eliza in the early 1920s and worked as a packer. He married a divorcee, Florence May Rule (nee Good) in 1925 in Lithgow. It appears Jaggs remained in Queensland for the remainer of the decade until he and Eliza joined Florence and her son Norman Edgar Rule in Bondi around 1930. The family moved to Vaucluse a few years later. Jaggs took up employment as a taxi driver and had driving jobs for the remainder of his working days.
Jaggs died in May 1964 and was buried at the Eastern Suburbs Memorial Park.
