The Narborough Research Group site states the following in relation to letters sent home by 2/AM Williams.
"It may be of interest to note that in one of his letters, dated 3rd January 1917, Williams writes, ‘Captain Ball DSO, the Zeppelin strafer, is in our squadron now, we feel quite honoured.’While at Narborough, Captain Ball crashed an Avro, escaping with cuts to the face, and his passenger with a broken leg. ‘Faulty rigging was his explanation, so someone is in for a hot time..."
Wikipedia states that Ball returned from France in October 1916 on leave from the Front after serving with No. 11 Sqn. It goes on to state that he was then posted to No.56 Sqn, which deployed to the Front in April of 1917. source
There is no official record of Cpt. Ball having joined or been apart of 59 Sqn. Furthermore, 56. Sqn were not stationed at Narborough till after the war in 1919.
If you have any information about Cpt. Ball, please contact me, thank you.
