"Two heroes of Erin, abhorrent of slaughter, Improved on the Hebrew command; One honored his wife, and the other his daughter, That 'their days might be long on the land.'"
For several years after the duel with D'Esterre, O'Connell was almost alone in the struggle for Emancipation. His practice steadily increased, and his legal knowledge, ability and tact, united with wondrous art in the examination of witnesses, and great influence with juries (by the union of a species of rhetoric consisting of common sense, humour, and rough eloquence, cemented together by a good share of "Blarney"), soon made him a very successful barrister. Whenever a Catholic victim was to be defended or rescued, whether an Orange oppressor was to be assailed and punished, O'Connell was in the van. The Catholics readily took him as their champion, and he won their gratitude by his services, and gained their personal attachment by a good humour which nothing could daunt, and a plain, straightforward, affectionate manner of eloquence which went directly home to their hearts. To this hour it is a moot point whether the Irish had greater admiration for his talents, gratitude for his services, confidence in his fidelity, or attachment for his person.
He continued increasing in influence for many years. From 1815, until he relinquished most of his practice in 1831, the annual income from his professional pursuits cannot have averaged less than from £6000 to £8000--an immense sum for a lawyer to make in Ireland. No man could make such an income, except one who was at once an excellent Nisi Prius pleader, as well as a good Crown lawyer. He united the highest qualifications of both. He could wield at will immense power over a jury, and argue with a success rarely equalled, so as to reach the understanding of a judge. Hence, he had the most extraordinary versatility. You would see him at one o'clock joking a jury out of a verdict in the Nisi Prius court, or familiarly laying down cases for the information of the judge; and, the next hour, you might behold him in the Crown court, defending an unhappy man accused of murder, and exercising a caution and prudence in his unparalleled cross-examination of witnesses which would alike surprise and please. No man could more readily get the truth from a witness, or make him say only just as much as suits the particular point he had in view.
