There is a brief reference to this officer in
Canadian Airmen and the First World War by S.F.Wise, but the name is spelled Urich for some strange reason. About the only additional information beyond what you already have is that Urich/Uhrich was from Winkler, Manitoba, and had arrived on station with 28 Squadron on 22 June 1918, just two days prior to his death. During this period, the Camels of 28 Squadron were heavily involved supporting ground attacks in the area of the bridges over the Piave River. Not much help I fear.
