The two officers whose photographs are here reproduced are sons of the Hon. Joseph Cook, formerly Prime Minister of Australia, and the nursing sister is the wife of Captain Cook, who recently returned to the front inter a few months' visit to Sydney. When war broke out Capt. Cook, who was then an architect in the Home Affairs Department, immediately volunteered. At first he was turned down, but on making a second attempt was accepted, and went into camp on 19th August, 1914. Within three months he was granted a commission in the 2nd Battalion, with which he left Sydney with the first lot of A.I.F. in October. In the landing at Gallipoli thee following April he was wounded, but was able to return to the firing line three weeks later, with the rank of captain. Shortly afterwards he was again injured, and was laid up for a week or two, but was back in time to take part in the famous Lone Pine engagement. He came through the great charge safely, only to be wounded during the counter-attack the following day. The injury was a serious a one in the scalp, and rendered him unfit for action for twelve months. Sister Cook, whom he had married just before leaving for the front, is a Red Cross nurse. She left with the first batch of Australian nurses on the Kyarra, and was in Alexandria when her husband arrived there. He was unconscious for over a week, and she nursed him back to convalescence. The two of them went to England on furlough, but Sister Cook did not remain there long, returning to Egypt immediately her husband was out of danger. After several months at Abbey wood Captain Cook returned to Sydney early this year, and was surprised to find that his wife - who in the meantime had gone to France with the Australians - had arrived in Sydney a few days earlier on transport duty. Sister Cook went to the Randwick Military Hospital tor a time before returning to France last July. Captain Cook went into camp for a brief period, then left with reinforcements for his battalion early last month. Both Captain Cook and his wife have been mentioned in despatches. Lieutenant Joseph Cook, who is an accountant by profession was in London when war broke out. He enlisted in 1914, and went into training with the Inns of Court Officers' Training Corps. Some time later he was granted a commission in the 5th North Staffordshires, and while in camp acted as assistant adjutant to the regiment. He went to France in July last.
