The Prince was, though, sometimes thought to have overstepped the still un-cemented bounds of constitutional monarchy in Canada, particularly in his carrying out of the ceremonial duties of the Commander-in-Chief during the First World War. Still, Prince Arthur stressed the importance of Canadian military contributions, promoting military training and readiness for Canadian troops, but also sought to enhance charity at home. To put this preaching into practice, the Duchess of Connaught, in addition to working for the Red Cross and other organisations, for Christmas in 1915 sent a card and a box of maple sugar to every Canadian serving overseas. She also had a knitting machine at Rideau Hall, on which she made thousands of pairs of socks for soldiers. Prince Arthur was active in auxiliary war services and charities, conducted a number hospital visits, and, following the war, commissioned a stained glass window, located in St. Bartholomew's Church, next to Rideau Hall, in memory of the Government House staff who lost their lives during the war. In the United Kingdom, the King and Queen visited with Canadian troops stationed there, as well as with the nurses of Canada's Red Cross Hospital.
