Husband of Mrs. E. D. Coleby, of Sydney-on-Vaal
Col (rt) Graham du Toit Last Post 12 Jun 2024: 71322556BT Staff Sergeant Donald Norman Coleby, Regiment Groot Karoo, Died of multiple shrapnel wounds 10 km south of Cuvelai. Company lured into a well dug-in ambush by SWAPO/PLAN Typhoon Brigade; while withdrawing across the Cuvelai River a Soviet 82 mm mortar exploded near him; succumbed while being evacuated to the Medical Aid Point just north of Mupa, age 27. ROH is KIA by machine-gun fire in an ambush near Vinticette — not overwritten.
Lance Graven, ROH story 16 Aug 2017: independently corroborates S. Porter's 2010 mortar-bomb correction (retreating from an ambush when a mortar bomb landed among them).
4 Sep 2026: Unit leftover "Regiment Groot Karoo" (a named regiment, not a sub-unit) moved to Regiment. Corps unchanged.
25 Sep 2026, Unit2 service-branch sweep: the stored Secondary Unit "Army" was CLEARED as a duplicate. It was not a sub-unit, it was a service-branch word repeating what the Branch column already says. Secondary Unit is for sub-units -- a company, a squadron, a commando -- and this record's branch of service is unchanged at "Army".
