Doyle, who joined the army in 1794 aged 13 and saw service in the Irish rebellion of 1798, was nephew to the distinguished generals Welbore Ellis Doyle and Sir John Doyle, Member for Newport, Isle of Wight, 1806-7, a founder member of the Irish Whig Club, whom he served as aide-de-camp during the Egyptian campaign, 1800-1, and as inspector-general of the Guernsey militia, 1805-9. He fought with distinction in the Peninsular wars in the joint service of the English and Portuguese armies (in which he was made lieutenant-colonel in 1809), commanding the 16th Portuguese infantry regiment under the duke of Wellington and subsequently the 6th Portuguese brigade. He retired from the Portuguese service in 1814 but did not return to Ireland until 1816; it was later reported that he had spent a fortune on ‘improvements for the benefit of Portugal, by making public roads, instituting mail coaches, and establishing steam communication’.
On 5 June 1823 Doyle informed Wellington of his departure for Portugal in a chartered steamer, the Royal George, in which he took dispatches to Dom Pedro’s family at Cadiz. He remained in the service of Pedro until May 1828, when he was imprisoned in a dungeon in Lisbon by the de facto government of Dom Miguel. On 24 July Sir John Doyle requested Wellington’s assistance in securing his release and, following the intervention of Lord Aberdeen, the foreign secretary, and representations by English merchants in Lisbon, he was liberated and banished from Portugal.
At the 1831 general election Doyle came forward for county Carlow as a ‘reformer’. A ‘victim of Dom Miguel’s tyranny’, he promised to emulate his uncle, whose pro-Catholic views he shared. A contest was averted at the last minute and he was returned unopposed.
abominably treated by Dom Miguel and has been a little cavalierly dealt with here at the foreign office respecting his claims on Portugal. A very little will make him turn from a zealous friend to be a bitter enemy and these things should be avoided ... He is a bore but I believe an honest fellow and has in Portugal been horridly treated.
Add. 51786.
Doyle voted for the second reading of the reintroduced ministerial reform bill, 6 July, and gave general support to its details, though he was in the minority for the disfranchisement of Saltash, 26 July, and absent from the division on the inclusion of Guildford in schedule B, 29 July, having protested the previous night that ‘if we are to go on, night after night, in this way’, the ‘bill will have the effect of destroying all our constitutions’. He argued that it was ‘false economy’ to withdraw the ‘paltry grant’ to Maynooth, 8 July. He contended that if ministers had heeded his advice to investigate the ‘irregularities’ of the Carlow election by appointing ‘one or more magistrates unconnected with the county and its party politics’, the atrocity at Newtownbarry in the neighbouring county of Wexford would not have occurred, 25 July. That day he voted against the grant for the Society for the Propagation of the Gospels in the colonies. On 27 July he attacked the government’s ‘apathy with respect to Portugal’ and their ‘much-boasted system of non-interference’, which had been ‘anything but the order of the day’. He divided against disqualification of the Dublin election committee, 29 July. He asserted that the ‘greatest illiberality prevails among many of the Protestant clergymen in Ireland’, citing the example of a Carlow rector who had declined to distribute his money to the poor because Doyle supported reform, 5 Aug. He denounced the ‘present mode of administering justice in Ireland’, 10 Aug., and declared that nothing could be ‘so ruinous and destructive to a country as the present grand jury system’, 29 Sept. He divided against the Irish union of parishes bill, 19 Aug., and for legal provision for the Irish poor, 29 Aug., and welcomed the appointment of Lord Duncannon* as lord lieutenant of county Carlow, 6 Oct. He voted for the third reading of the reform bill, 19 Sept., its passage, 21 Sept., and Lord Ebrington’s confidence motion, 10 Oct. 1831.
Doyle contended that if the Irish reform bill was fair ‘agitations would cease’, 12 Dec. 1831. He voted for the second reading of the revised English reform bill, 17 Dec., supported its details, and divided for its third reading, 22 Mar. 1832. He voted with ministers on the Russian-Dutch loan, 26 Jan., 12, 16, 20 July (as a pair), and was in their majority against a motion for papers on Portugal, 9 Feb., when he spoke of the need for an inquiry and denounced Miguel as a ‘little petty tyrant’ whose supporters were ‘the decided enemies of everything British and liberal’. He condemned the ‘nefarious’ activities of Spain in assisting ‘the present usurper on the bloodstained throne of Portugal, notwithstanding its pledge to the contrary to France and England’, 26 Mar. On 13 Apr. Lord Palmerston, the foreign secretary, took up his claim for compensation and instructed the British consul at Lisbon to demand £6,900 from the Portuguese government.
In September 1832 Doyle accepted an invitation to join the army of Dom Pedro as his aide-de-camp and announced his retirement from his seat; he was gazetted a major-general at Oporto, 9 Nov.
