[2][3] A member of the Gwalior royal family's household,[4] he attended St. Xavier's High School in Bombay, after which he joined Jesus College, Cambridge in the Lent term of 1915 to read history and law.

[1] After securing a recommendation from Brigadier-General Sefton Brancker, Welinkar enlisted in the Oxfordshire and Buckinghamshire Light Infantry on 13 February 1917, and was posted to No.

Having sustained bullet wounds and a leg fractured below the knee, he had died at a German field hospital in a town named "Rouvroy" on 30 June 1918.

"[5] In March 1920, an RAF wing commander named Hilton unsuccessfully attempted to locate the exact "Rouvroy" where Welinkar had been buried.

Colonel Barton observed the exhumation and tentatively identified the remains as belonging to an RAF flying officer, based on the corpse wearing an airman's boots and watch.

The body was reinterred in Hangard Communal Cemetery Extension, and in February 1921 was conclusively identified as that of Welinkar after a search of German military burial records.
