Charles was the son of Joseph John Hall, a mining engineer, and Emily Eleanor Lewis, who lived at Westfield, Ashington, Northumberland. He was educated at the North Eastern County School, Barnard Castle, and Armstrong College, where he was preparing for the profession of a mining engineer.
His eldest brother was Captain Lewis Wigham Hall, R.F.C. and 1st Battalion the Border Regiment who flew continuously at the front for over twelve months and was subsequently appointed Flying Instructor.
Prior to his military service, Charles was a member of the University's Officer Training Corps whilst at Armstrong College, where he held an honorary instructor’s certificate and the medallion of the Royal Life Saving Society. Charles was gazetted 2nd Lieutenant, R.F.C. on 28/06/1916. He served with the Expeditionary Force in France and Flanders and was commissioned into the Royal Flying Corps, 60th Squadron.
Charles was killed in aerial combat on 7th April 1917 aged 18. According to his Squadron Commander, "He was leading a fighting patrol of six machines on the evening of the 7th. They most gallantly attacked a formation of hostile aeroplanes of much superior number, and two machines were brought down... we all liked your son immensely and miss him sorely." His body was found by an officer of the R.F.A. in the subsequent advance of the British two days later.
