[4] He was rewarded by an appointment to command the Illustrious, 74 guns, bearing the broad pendant of Commodore Broughton; and during the subsequent operations against Batavia, he bore a very distinguished part on shore, under the orders of Captain Sayer; particularly at the assault of Meester Cornelis, on 27 August 1811.

[7][8] On 10 September, Commodore Broughton joined Rear-Admiral Stopford, off Samarang; and in the course of the ensuing night, several of the enemy's gun vessels, lying in-shore, were attacked and destroyed by the boats of the squadron, under the directions of Captain Maunsell; whose post commission was confirmed by the Admiralty, on 7 February 1812.

[9] His next appointment was, on 24 or 25 August 1812,[10][5] to the Chatham, 74 guns, bearing the flag of Rear-Admiral Matthew Henry Scott, on the North Sea station; the command of which ship he retained till July 1814.

for the northern division of Northamptonshire, Colonel of the Northampton Militia, and Captain of the Kettering Yeomanry Cavalry: his second, William Wray Maunsell, Archdeacon of Limerick, married the eldest daughter of Charles Warburton, Bishop of Cloyne.

[4] During that period to be made a participator in many cutting-out affairs; but particularly on 11 July 1804, when, holding the rating of Master's Mate, he served with the boats of the Maidstone, Narcissus, and Seahorse, 10 in number, under the orders of Lieutenant John Thompson,[a][14] and assisted at the capture of 12 settees, lying at La Vandour, in the Bay of Hières, after a conflict, in which the British, encountered by a tremendous fire of grape-shot and musketry, as well from the vessels themselves as from a battery and the houses of the town, sustained a loss of 4 men killed and 23 (including himself, severely) wounded.

[b][4] He was promoted, as soon as he had accomplished his time, to a Lieutenancy, on 7 March 1805, in the Princess Royal, 98 guns, Captain Robert Carthew Reynolds, attached to the Channel fleet.

[4] Among the numerous prizes made by Maunsell in the sloop Procris, was the capture, in July 1810,[3][4] or else in 1809, of the Dutch Company's brig Wagster, of 8 guns, 4 swivels, and 86 men.

[4] Although the latter contrived to escape by hauling through the mud up the river, five of the armed vessels were boarded and carried, and the remaining one destroyed; this with a loss of only 11 men wounded, notwithstanding that the enemy, in addition to the fire of their guns, kept up a constant discharge of musketry.

[10] In the early part of 1812, on 7 February in which year he was confirmed to Post-rank, Captain Maunsell, in consequence of an attack of Batavian fever, returned to England; and on 24 or 25 August 1812,[10][5] was appointed to the Chatham, 74 guns, bearing the flag in the North Sea of Rear-Admiral Matthew Henry Scott, with whom he continued until 26 May 1814.

[10] Landing, accordingly, close to the palace, he managed to pass the guards unmolested, and, entering the presence-chamber, without introduction, had the good fortune to obtain a very flattering audience, and fully to carry out the object of his mission.

; and in April 1844, as a tribute to "his high personal character, and his eminent professional service", he was spontaneously appointed by the prime minister, Sir Robert Peel, a Commissioner of Greenwich Hospital.
