[3][4] Jan Kubiš, having previously been an active member of Orel, started his military career as a Czechoslovak army conscript on 1 November 1935 by 31st Infantry Regiment "Arco" in Jihlava.

Following the Munich Agreement and demobilisation, Kubiš was discharged from army on 19 October 1938 and returned to his civilian life, working at a brick factory.

At the eve of World War II, on 16 June 1939, Kubiš fled Czechoslovakia and joined a forming Czechoslovak unit in Kraków, Poland.

A month after the German victory in the Battle of France, Kubiš fled to Great Britain, where he received training as a paratrooper.

Since this was unknown after World War II, Karel Čurda, the member of their squad who betrayed them to the Nazis, was coincidentally also buried at the cemetery.

As the car braked in front of him, Kubiš threw a modified anti-tank grenade[8] (concealed in a briefcase) at the vehicle; he misjudged his throw.

Heinz Pannwitz, the German detective charged with capturing at least one of the perpetrators alive, later stated: He had tried to use poison on himself but apparently lost consciousness before he could do so.

[14] In revenge, the Nazis murdered 24 family members and close relatives of Jan Kubiš in the concentration camp, Mauthausen: his father, both full and half-siblings, including their wives and husbands, cousins, aunts and uncles.

[16][17][18] There are streets named after Jan Kubiš in the cities of Prague (close to the Operation Anthropoid Memorial), Pardubice, Tábor, Třebíč and other places.

[22][23] Coinciding with the release of the film Anthropoid, campaigners called for Kubiš's and Gabčík's bodies to be identified and exhumed from the mass-grave at the Ďáblice Cemetery, Prague, and to be given a dignified burial fitting "the heroes of anti-Nazi resistance".

[24][25] A memorial stone for Jan Kubiš and Jozef Gabčík can be found in the grounds of St John the Baptist Church in Ightfield (ref W9VR+FJ Whitchurch) on Google Maps.
