War strategies of the generals On 26 November 1838, Andries Pretorius (1798–1853) was appointed as Commander of 64 wagons and 464+ heavily armed Boer combatants directed against Dingane at
UmGungundlovu with Jan Gerritze Bantjes (1817–1882) as his war secretary. By December 1838, Prince Mpande and 17,000 followers had already fled from Dingane, who was seeking to assassinate Mpande. In support of Prince Mpande as Dingane's replacement, Pretorius' strategy was to target Dingane only. To allow Prince Mpande to oust King Dingane through military might, Pretorius had first to weaken Dingane's personal military power base in UmGungundlovu. Dingane's royal residence at UmGungundlovu was naturally protected against attack by hilly and rocky terrain all around, as well as an access route via
Italeni passing through a narrow
defile. Earlier on 9 April 1838, a Trekker horse commando without ox wagons, thereafter called the "Flight Commando", had unsuccessfully attempted to penetrate the UmGungundlovu defense at nearby Italeni valley, resulting in the loss of several Trekker lives. Trekker leader
Hendrik Potgieter had abandoned all hope of engaging Dingane in UmGungundlovu after losing the battle of Italeni, and subsequently had migrated with his group out of Natal. To approach UmGungundlovu via the Italeni defile with ox wagons would force the wagons into an open column, instead of an enclosed
laager as successfully employed defensively at
Veglaer on 12 August 1838. The military commander during Dingane's attack on Veglaer was
Ndlela kaSompisi. The highly experienced general Ndlela had served under
Shaka, and was also prime minister and chief advisor under Dingane. Ndlela with his 10,000 troops had retreated from Veglaer, after three days and nights of fruitless attempts to penetrate the enclosed Trekker wagon laager. General Ndlela personally protected Prince Mpande from Dingane's repeated assassination plans. King Dingane desired to have his half brother Mpande, the only prince with children, eliminated as a threat to his throne. Ndlela had to let Pretorius come close to UmGungundlovu at Italeni and lure the Trekkers into attack. Ndlela was not to attack the Trekkers when they were in a defensive wagon laager position, especially not during the day. The problem for Pretorius was that he had somehow to find a way to make Dingane's soldiers attack him in a defensive laager position at a place of his choice, far away from UmGungundlovu and Italeni. On 6 December 1838, 10 days before the Battle of Blood River, Pretorius and his
commando including
Alexander Biggar as translator had a meeting with friendly Zulu chiefs at
Danskraal, so named for the Zulu dancing that took place in the Zulu kraal that the Trekker commando visited. With the intelligence received at Danskraal, Pretorius became confident enough to propose a
vow to God, which demanded the celebration, by the commando and their posterity, of the coming victory over Dingane. The covenant included that a church would be built in honour of God, should the commando be successful and reach UmGungundlovu alive in order to diminish the power of Dingane. Building a church in Trekker emigrant context was symbolic for establishing a settled state. After the meeting with friendly Zulu chiefs at Danskraal, Pretorius let the commando relax and do their washing for a few days at Wasbank till 9 December 1838. From Wasbank they slowly and daily moved closer to the site of the Battle of Blood River, practicing laager defence tactics every evening for a week long. Then, by halting his advance towards UmGungundlovu on 15 December 1838, 40 km before reaching the defile at Italeni, Pretorius had eliminated the Italeni terrain trap.
Location and preparation On Saturday, 15 December 1838, after the Trekker wagons crossed the
Buffalo River 10 km SW of the actual battle site and still from their target UmGungundlovu, an advance scouting party - including Pretorius - got news of a large Zulu force in rugged terrain to the east trying to lure the Boers into a trap, as had been the case in April the same year with fatal consequences. While Cilliers wanted to ride out and attack, Pretorius declined the opportunity to engage Dingane's soldiers away from their base as had been the trap at Italeni valley. Instead, Pretorius decided on a fortified laager on the terrain of his own choosing, in the hope that general Ndlela would attack Pretorius on his terms rather than the other way around. As the site for the defensive wagon laager, Pretorius chose a defensible position close to a vertical 8m descent into a deep hippo pool in the Ncombe River, providing excellent protection on two sides. The wide-open area to the front of the laager provided absolutely no cover for an attacking force. The battle was set with the laager protected on two flanks. As usual, the ox-wagons were drawn into the typical protective
laager. Movable wooden barriers and ladders which could be quickly opened for cavalry were fastened between the wagon wheels to prevent intruders, with two smoothbore, short barrel artillery pieces positioned at the corners. Andries Pretorius had brought a 6-pound naval
carronade with him from the Cape, mounted on a
gun carriage improvised from a wagon axle, and named
Grietjie. The other ordnance piece is unknown, but is currently depicted as a 4-pound smoothbore
cannon, by then obsolete in most European armies. Both were used to fire devastating
grapeshot. As evening approached, a thick mist settled over the wagon site, above which the sky was clear. According to Afrikaner traditions, the Zulu were afraid to attack at the night due to superstitions and the eerie glow of lamps which the Boers hung on
sjamboks [whip-stocks] around the laager. Whether or not there is any truth in this, historian S.P. Mackenzie has speculated that the Zulu held back until what they perceived as the necessary numbers had arrived. Some of the Zulus only arrived near sunrise by following the tracks of the wagons. - crossed the Ncome River and started massing around the encampment, while the elite forces of senior general Ndlela did not cross, thereby splitting the army in two. ==Battle==
