The citation for Johannes Conga's deed of bravery which merited the Honoris Crux (Postumous) reads:
On 12 September, 1979, a security patrol of section strength was sent from a company base to secure a particular area. The platoon commander was 2/Lt. G.M. van Niekerk. Two men from another platoon accompanied them, 2/Lt. Coetzee and Rifleman Johannes Conga. The Patrol moved in formation, with the two men alongside the platooncommander, when they were ambushed by about 50 of the enemy.
Heavy machine-gun and rifle fire poured into them. The two officers were pinned down and could not exercise control over the situation or reply to the fire.
Rifleman Conga then stood up and began shooting, while moving sideways, so drawing the enemy fire away from the officers onto himself, to allow the officers to reorganize the defence.
The enemy machine-gun had switched from the officers to Conga when he bravely stood up and took them on. Lance Corporal McGrath then managed to shoot the PLAN machine-gunner.
The tables were turned and ten of the enemy killed.
Conga was mortally wounded and was posthumously awarded the Honorix Crux.
