On the 31st of October the regiment embarked, under the command of Lieut.-Colonel Sir Edward Butler, from Plymouth, for Guernsey, of which island Major-General Doyle had been appointed to the command and to the Lieutenant-Governorship.
The British Government, having ascertained that the King of Spain had engaged to furnish powerful aid to France, felt itself compelled to consider Spain as an enemy, and accordingly issued orders for intercepting some frigates off Cadiz, which were on their way to France with cargoes of treasure: a declaration of war was consequently issued by the Court of Madrid against Great Britain on the 12th of December 1804.
The establishment of the Eighty-seventh regiment, which had been authorised to receive men raised in certain counties of Ireland, under the Act of Parliament, dated 14th July 1804, termed the “Additional Force Act,” was augmented by a second battalion, of which a distinct account is commenced at page 41.[6]
1805.
On the 10th of March 1805, a detachment, consisting of twenty-eight serjeants, fifteen drummers, and five hundred and twenty-eight rank and file, being drafts from the levy then raising in the county of Mayo by the Honorable H. E. Browne, embarked from Ireland for Guernsey, and joined the first battalion on the 15th of April following, thus considerably augmenting the effective strength of the Eighty-seventh regiment.
1806.
On the 2nd of November 1805, the first battalion embarked from Guernsey, and proceeded to Portsmouth.
The first battalion of the Eighty-seventh regiment embarked at Portsmouth on the 23rd of July 1806, and proceeded to Plymouth, where it disembarked on the 6th of September following. On the 12th of that month it embarked for South America, under the command of Lieut.-Colonel Sir Edward Butler; the effective numbers were, fifty-three serjeants, eighteen drummers, and eight hundred and five rank and file.[7]
1807.
The first battalion arrived in the Rio de la Plata in January 1807, and disembarked on the 16th of that month near Monte Video, where it took up a position in advance, protecting the breaching batteries, it having been arranged between Brigadier-General Sir Samuel Auchmuty and Rear-Admiral Stirling to lay siege to the place. The piquets of the Eighty-seventh, under Major Miller, were attacked by the Spaniards, who were defeated with great loss. On the 3rd of February, a practicable breach being made, the troops proceeded to storm the town, which was carried, and the citadel soon afterwards surrendered.
