The interior contains some interesting sepulchral monuments, among which is one of Roubiliac in the reliefs to the memory of Viscount Bolingbroke and his second wife, niece of Madame de Maintenon, both lie in the family vault in St. Mary's Church. The epitaphs on himself and his wife were both written by Bolingbroke. That upon himself is still extant in his own handwriting in the British Museum, and is as follows:—"Here lies Henry St. John, in the reign of Queen Anne, Secretary of War, Secretary of State and Viscount Bolingbroke; in the days of King George I. and King George II. something more and better. His attachment to Queen Anne exposed him to a long and severe persecution; he bore it with firmness of mind, he passed the latter part of his life at home, the enemy of no national party, the friend of no faction, distinguished under the cloud of proscription, which had not been entirely taken off by zeal to maintain the liberty and to restore the ancient prosperity of Great Britain." Another monument commemorates the descent and preferments of Oliver St. John, Viscount Grandison, who was the first of the family that settled at Battersea. When studying the law at one of the Inn Courts, he killed in a duel the Captain of the Guard to Queen Elizabeth and Champion of England. "In 1648, Sir John St. John was buried at Battersea with such unusual pomp that the heralds were fluttered and commenced a prosecution against the Executor for acting contrary to the usage of arms and the laws of heraldry. William Riley, one of the heralds deposed 'that the funeral of the deceased was conducted in a manner so much above his degree that the escutcheons were more than were used at the funeral of a Duke; and that he never saw so many persons but at the funeral of one of the blood royal.' This burial is omitted in the register." In the south gallery is a monument to Sir Edward Wynter, an officer in the service of the East India Company in the reign of Charles 2nd, on which is recorded an account of his having singly and unarmed killed a tiger, and on foot defeated forty Moors on horseback. He appears to have been a friendless youth but obtained his promotion by virtue of his intelligence, courage and good conduct as the epitaph states:—

"Born to be great in fortune as in mind,
Too great to be within an Isle confin'd,
Young, helpless, friendless seas unknown he tried;
But English courage all those wants supplied.
A pregnant wit, a painful diligence,
Care to provide, a bounty to dispence,
Join'd to a soul sincere, plain, open, just,
Procur'd him friends, and friends procured him trust;
These were his fortune's rise, and thus began
This hardy youth, rais'd to that happy man,
A rare example and unknown to most
Where wealth is gain'd and conscience is not lost.
Not less in martial honour was his name—
Witness his actions of immortal fame!
Alone, unarm'd a tiger[1] he oppress'd
And crush'd to death the monster of a beast;
Twice twenty mounted Moors he overthrew
Singly on foot; some wounded, some he slew,
Dispers'd the rest—what more could Samson do?
True to his friends, a terror to his foes
Here now in peace his honour'd bones repose."
Vita Peregrinatio.

[1] Being attacked in the woods by a tiger, he placed himself on the side of a pond, and when the tiger flew at him, he caught him in his arms, fell back with him into the water, got upon him, and kept him down till he had drowned him.

He died March 2nd, 1685-6, aged 64.

Near at hand is a monument—a small statue of a mourning female leaning upon an urn—erected by the benevolent James Neild, in memory of his wife Elizabeth, who died 30th of June, 1791, in her 36th year. The epitaph states:—

Here low in beauteous form decay'd
My faithful wife, my love Eliza's laid;
Graceful with ease, of sentiment refin'd,
Her pleasing form inclos'd the purest mind!
Round her blest peace, thy constant vigils keep
And guard fair innocence her sacred sleep,
'Till the last trump shall wake the exulting day.
To bloom and triumph in eternal day.
Conjux Mærens Posuit.

And of her father, John Camden, Esq., whose son, John Camden Neild, lived in Cheyne Walk, Chelsea, and bequeathed to Queen Victoria the whole of his property, £500,000.

At the east end of the north gallery is a beautiful marble monument most elaborately sculptured sacred to the memory of Sir John Fleet, Knt., Alderman of the City of London. He was unanimously elected Lord Mayor of the City in 1693. He received Royal favours, and all ranks of the greatest honour and esteem from his fellow citizens, having been one of their representatives in Parliament thirteen years, and constantly interested in their highest stations, in which offices and honours he was universally applauded. He was a merchant and just magistrate, constant to church, loyal to his Prince, and true to his country. He was fortunate and honest, bountiful in charity a generous benefactor and a faithful friend.—Obit 6 Julii 1712. Ætat: 65.

Another tablet is erected to the memory of Margaret Susanna Pounsett, wife of Henry Pounsett, Esq., of Stockwell, in this County, and eldest daughter of Richard Rothwell, Esq., of this Parish; Alderman of the City of London and High Sheriff of the County of Middlesex: she died on the 22nd day of March, 1820, in the 32nd year of her age, leaving two sons and three daughters. Her numerous amiable and exemplary qualities, endeared her to her family in her life—Her Christian piety and cheerful resignation alone consoled them in her death. Also of Ellen Anne Pounsett, her second daughter, who died the 7th of December, 1834, aged 22.

In the west gallery is a marble tablet sacred to the memory of Richard Rothwell, Esq., Alderman and formerly High Sheriff of the City of London, and County of Middlesex; who departed this life most deeply regretted, July 26th, A.D. 1821, in the 60th year of his age. In the public station which he filled of Magistrate and Sheriff, his strict integrity, his splendid liberality, and his genuine philanthropy, justly merited and procured the highest esteem, and warmest approbation of his fellow citizens. In his private character he was respected for the vigor of his mind, the solidity of his judgment, and the uprightness of his principles, and beloved for the urbanity of his manners, and the benevolence of his heart. In him the perplexed found an able counsellor, and the distressed an active friend. His feelings were tenderly alive to the important truths of religion, and while punctual in the performance of the duties of this life he placed his sole reliance on the merits of his Redeemer for happiness in the life to come.
