Christophe, therefore, as soon as he heard that he had a rival in Pétion, rallied his forces, and started for Port au Prince, to meet his enemy, and obtain by conquest what had been refused him by right of succession; and, as he thought, of merit. Pétion was already in the field; the two armies met, and a battle was fought. In this contest, the impetuosity of Christophe’s attack was more than a match for the skill and science of Pétion; and the new president was defeated in his first enterprise against the enemy of his government. The ranks of Pétion were soon thrown into irretrievable confusion, and in a few minutes they were driven from the field--Pétion himself being hotly pursued in his flight, finding it necessary, in order for the preservation of his life, to exchange his decorations for the garb of a farmer, whom he encountered on his way, and to bury himself up to the neck in a marsh until his fierce pursuers had disappeared. After this signal success, Christophe pressed forward to Port au Prince, and laid siege to that town, in the hope of an easy triumph over his rival. But Pétion was now in his appropriate sphere of action, and Christophe discovered that in contending against an experienced engineer in a fortified town, success was of more difficult attainment than while encountering the same enemy in the open field, where his science could not be brought into action. Christophe could make no impression on the town; and feeling ill assured of the steadfastness of his own proper government at Cape François, he withdrew his forces from the investment of Port au Prince, resolved to establish in the North a separate government of his own, and to defer to some more favorable opportunity the attempt to subdue his rival at Port au Prince. Thus placing themselves in hostile array against each other, the two chiefs of Hayti employed themselves in strengthening and establishing their respective governments, and in attempts to gain over the different parts of the Island to an acknowledgment of their authority. Christophe assumed the title of President of the State, and Pétion, of the Republic; and the inhabitants of the country conferred their allegiance according to the opinions of their chiefs, or the places of their residence.
