Re Cadet Arthur Richardson
Onn the 3rd inst. Arthur Richardson a Cadet at Camp Mohawk near Deseronto fell down a hole or pit about 16 feet deep and was illed. This pit which was constructed for drainage purposes was unguarded and unlighted, owing, in my opinion, to the negligence of George Vandewater the Foreman – Imperial Munitions Board at Camp Mohawk.
The pit lay close to the Cadet Barracks and adjacent to a walk over which 35 men were accustomed to go, 10 to 15 deep and about 10 by 5 feet wide at the top, being narrower at the bottom and containing some water.

Richardson was born in Gateshead, England in 1890, the son of William Summerbell Richardson and Dorothy (née Burn). He attended the Royal Grammar School at Newcastle-upon-Tyne from 1902. He moved to New York in 1913, arriving on the RMS Adriatic on October 3rd, 1913 (five years to the day before he died). He was a chartered accountant by profession.

Arthur joined the Royal Flying Corps on April 11th, 1918 in Winnipeg (technically by then it was the Royal Air Force) and was officially appointed to the Corps on April 15th in Toronto with the regimental number 171458. He was five feet ten and three quarter inches tall, with a dark complexion, black hair and brown eyes.

He was buried in Bellefontaine Cemetery, St. Louis, Missouri. A blog post on the Sacrifice site explains why.
