Ignatius "(Oom) Naas" Stephanus Ferreira (21 March 184418 February 1900, Oom meaning Uncle in Afrikaans) was an Orange Free State Boer war general[1] and Commander-in-Chief,[2] who was fatally shot at the Battle of Paardeberg.[3] Naas Ferreira should not be confused with his son and namesake Ignatius "Natie" Stephanus Ferreira (1875 – 1947), the gold miner Ignatius Philip Ferreira (1840 – 1921), and Boer general J. (Joachim) Ferreira (1835 – 1917).
Naas Ferreia was the eldest child among three sons and four daughters of Petrus Marthinus Ferreira (Uitenhage, Port Elizabeth, Eastern Cape, South Africa, 6 September 1818Winburg, Lejweleputswa, Orange Free State, August 23, 1898) and Christina Elizabeth Ferreira (Uniondale, Western Cape, 10 November 1824Senekal, Orange Free State, 11 March 1904). Ferreira married Anna Margaretha Rademeyer (Humansdorp, Western District, Eastern Cape, 14 October 1843Ladybrand, Motheo, Free State, 18 June 1911)[4] and fathered three sons and two daughters.[5]
In the Second Boer War (1899 – 1902) Ferreira was the leader of the Ladybrand Commando and the Commander-in-Chief (Afrikaans: Hoofd Kommandant) of the Orange Free State. He took part in many early battles won by the Boers, such as the Battle of Modder River (Afrikaans: Slag van die Twee Riviere|lit=Battle of the two rivers, 28 November 1899), and the Battle of Magersfontein (11 December 1899). There he distributed the Boer troops more evenly over their hidden trenches for a maximum lethal result when the British under Lieutenant General Lord Methuen fatally attacked in a close formation.[6]
On January 8, 1900, Ferreira was elected to take over the command of the Siege of Kimberley from Boer general Cornelis (Kerneels) Janse Wessels (11 January 1842 - 10 October 1914).[7] [8] [9] However, when the British relief expedition of Lieutenant-General John French arrived, Ferreira was left with only 200 men and had to retreat, so that Kimberley was liberated on February 15, 1900. He then moved southwards with his troops near Boshof to join Christiaan de Wet's force, as it was thought that the British would try to break through eastward to Bloemfontein.[10] [11]
At Paardeberg, Ferreira commanded the Boer burghers from Hoopstad and Ladybrand[12] to help Piet Cronjé's 4000-odd troops escape from their embattled position in the north bank of the Modder River. However, when Ferreira was waking up a dozing guard in his camp in the early morning with the rifle butt, he was fatally shot in the stomach by accident when the startled guard instinctively groped the rifle.[13] [14] Ferreira was succeeded as commander-in-chief of the Orange Free State troops by Christiaan de Wet on February 19, 1900.[15] Ferreira's son and namesake "Natie" continued to serve as a secretary to Boer general Koos de la Rey.
