Piet Retief, one of the leaders of the voluntary exiles, had published a proclamation in the following terms before he joined the trek: "We quit this Colony under the full assurance that the English Government has nothing more to require of us, and will allow us to govern ourselves without its interference in the future. We are now leaving the fruitful land of our birth, in which we have suffered enormous losses and continual vexation, and are about to enter a strange and dangerous territory; but we go with a firm reliance on an all-seeing, just, and merciful God, whom we shall always fear and humbly endeavour to obey." This was high language, yet after-events proved that a steady, consistently fair treatment on our part would even then have reconciled these men to a permanent continuance of British sovereignty. Unfortunately, our policy oscillated painfully between irritating interference and excessive timidity. First of all attempts were made to stop the trek by force, then to compel the trekkers to return by cutting off their supplies and ammunition, then to throttle their development of the new lands north of the Orange and Vaal Rivers by calling into being fictitious native States on a huge scale in the midst of and around them, then tardily to repair the disastrous effects of this policy; but not before it had led to open hostilities (1845). Hostilities, however, had this temporarily good result, in that it brought to the front one of the ablest and wisest of the Cape Governors, Sir Harry Smith, who defeated the Boers at Boomplatz in 1848, established what went by the name of the Orange River Sovereignty, and in a year or two secured such good and peaceful government within its borders as to attract considerable numbers of English and Scotch colonists. The malcontents retired across the Vaal. Then came an abrupt change of policy in the Home Government, a sudden desire actuated mainly by fear of more native wars, to cancel all that was possible of our commitments in South Africa. The Transvaal, by the Sand River Convention, was declared independent in 1852, the Orange Free State, by the Convention of Bloemfontein, in 1854. This was to rush from one extreme to the other. It was as though in 1847 we had erected Quebec into a sovereign State instead of giving it responsible government under the Crown, or as if in 1843 we had been so deeply convinced by O'Connell's second agitation for repeal that we had leapt straight from coercive government to the foundation of an independent Republic in Ireland, instead of giving her the kind of Home Rule which she was asking for.
