After the war, Jackie was given the rank of corporal, and the Pretoria Citizens Service Medal, then he died a year later in a home fire.

Jackie's human story started in the early half of the 1910s when South African Albert Marr found the baboon around his farm.

Marr's commanding officers, to the soldiers' surprise, acquiesced, so Jackie was made a mascot for the 3rd South African Infantry Regiment (Transvaal) and brought everywhere with them.

[3] Jackie and Marr survived a battle where the casualty rate was 80 percent, in Delville Wood, early in the Somme Campaign.

[3] When Marr was serving in Egypt he was shot in the shoulder at the Battle of Agagia, 26 February 1916, while Jackie was with him, licking the wound as they awaited help.
