On 7 March , Wellesley was gazetted ensign in the 73rd Regiment of Foot. In October, with the assistance of his brother, he was assigned as aide-de-camp, on ten shillings a day twice his pay as an ensign , to the new Lord Lieutenant of Ireland Lord Buckingham. He was also transferred to the new 76th Regiment forming in Ireland and on Christmas Day, , was promoted to Lieutenant.
During his time in Dublin his duties were mainly social; attending balls, entertaining guests and providing advice to Buckingham. Two years later, in June , he transferred to the 12th Light Dragoons, still as a lieutenant and according to his biographer, Richard Holmes, he also dipped a reluctant toe into politics becoming an MP for Trim in the Irish House of Commons and in he became a Captain and was transferred to the 18th Light Dragoons.
Arthur Wellesley, or Wesley, as he then styled himself, then left Dublin for active service in the Netherlands and apparently did not look back on his lost love. Nowhere in his correspondence for the interceding 12 year interval does he make any reference to Catherine Pakenham, or does a letter to or from her exist.
Do you think I ought to renew my offer? Supposedly, he then wrote at once to Miss Pakenham, renewing his proposal of marriage. She replied that, as it was so long since they had met, he had better come over and see her before committing himself, lest he should find her aged and altered. Sir Arthur replied that minds, at all events, did not change with years and hastened over to Ireland. Whilst the Duke possessed many laudable qualities, the ability to be a great husband and father was not amongst them.
He treated Kitty rather coldly beginning very early in their marriage. Supposedly, Wellington found the fact that Kitty herself did not disclose the engagement to him deceitful.
