Up to that time the settlers of the Cape Colony had only branched out as far as the Great Fish River. This was the limit of safety, since beyond lay trackless wastes and millions of savage natives noted for their hostility and cannibalism. Practically all these settlers were the ancestors of the present Boers.
As is occasionally the case in present times, it was the missionaries who caused the trouble that led to the breaking up of the old Boer homes in Cape Colony. A number of these religious gentlemen came out from England and lived for a short time in the Colony. On their return to London they misrepresented facts to the king to such an extent that a number of restrictive laws and regulations were passed. These made life impossible for the Boers, who have always been a freedom-loving people.
Finally about ten thousand of the burghers got together and commenced their exodus from Cape Colony into the unknown territory beyond the Great Fish River. The Zulus and Basutus met the first party, there was a bitter fight, and every Boer man, woman and child was massacred. In many cases, when the men realized that there was no hope, they killed their own womenfolk so that they might not fall into the hands of the savages.
This bloody tragedy did not deter the determined Boers. Other parties followed, and soon these pioneers founded various settlements. Every foot of their advance was gained by fighting, and the Boer conquest of the Transvaal and Orange Free State may well be said to have been won by the blood of freemen. Some of these expeditions settled in Natal and founded the city of Pietermaritzburg, named after their great leader, Pieter Maritz.
It was during the year 1830 that my grandfather joined the Great Trek and left Cape Colony with a large expedition led by Piet Retief and Piet Potgier. The party had much trouble with the Zulus, its progress being a continuous fight. On reaching the Vaal River, Potgier and Retief came to loggerheads and agreed to separate. Each had his own opinion as to where they ought to go, and each followed his own idea. My grandfather remained with Retief and thereby nearly lost his life. With my grandfather was his brother, Richard Charles O'Neil, after whom my father was named.
