Charles was educated at Manchester Grammar School and studied medicine at Manchester University. In 1909 he obtained his M.B., Ch.B., in 1911 the Diploma of Public Health, and in 1913 his certification as a M.D. He was also a member of the Manchester University Lacrosse Team. Charles became employed as demonstrator in anatomy at Manchester University and later as house physician and surgeon at the Children's Hospital, Pendlebury; the Manchester Royal Infirmary; the Manchester Consumption Hospital; the Ancoats Hospital; and the Royal Infirmary, Bradford, Yorkshire. Whilst working at the Royal Infirmary, Bradford, he obtained a commission in order to go the front as a surgeon. From that time he was employed in training field ambulance men until he left for Gallipoli in June 1915, when he began acting as Commanding Officer of the 2/3rd Field Ambulance. On July 30, 1915, he departed from Devonport, Devonshire, on H.M. Transport Royal Edward as part of a draft for the 1/3rd East Lancashire Field Ambulance, and was drowned when the ship was sunk by the German submarine U-14 on August 13, 1915. Charles was the youngest son of William and Sarah Marshall of Greenwood Lee, The Park, Cheadle Hulme, Stockport. Charles's father was employed as the Public Analyst for the Borough of Hyde, his laboratory was in Ladybrook Road. A Lieutenant Wilson wrote to him stating "They struck a mine coming from Alexandria and spent 3 or 4 hours in the water, before being picked up by a hospital ship and a destroyer. Am much afraid that Marshall who was with them went down with the ship. After seeing all his men off the ship and encouraging them, he was last seen leaning on the rail of Captain’s bridge, looking down quite calmly at them. He was so very tough and so much at home in the water, that we have not lost hope that he was picked up by some other vessel. It was very characteristic of him to get all the men off in the way he did and then to stem any panic among them by calmly standing about the bridge. It helped them a lot because several men have told me that after seeing him so calm they were led to look on the whole thing as more or less of a joke. He would fight for his life like a fiend when he got in the water." He also received a letter from Lieutenant F B Smith of the Field Ambulance, "Of the 50 men of our Ambulance, only 3 are lost. I have not told you what a corporal of our section has told me, that he saw Capt. Marshall, long after he himself was in the water, still on the highest deck with the captain of the ship, revolver in hand, encouraging and controlling the men. He had no need to use his weapon because discipline was splendid. The men knew his worth and not one but has spoken to me sadly of our loss. Such a cool courageous sticking to duty was characteristic of the man he was."
