Private Michael O'Sullivan
The background of this North Irish Horseman is not known at present.
The Silver War Badge register gives Sullivan's enlistment date as 15 December 1914. This may have been with a regiment other than the North Irish Horse, which he did not join until 12 May 1915 (No.1536).
Whether he served overseas with the regiment is also not clear. While the Silver War Badge register states that he did, I have not been able to locate a Medal Roll record to confirm this.
On 20 September 1916 O'Sullivan was discharged due to illness, being 'no longer physically fit for war service' (paragraph 392 (xvi), King's Regulations).
