Passage: John Silvester, the Recorder of London referenced the spectre of Napoleon Bonaparte and the burgeoning Napoleonic Wars in his announcement of Perring's appointment, stating that "At a time so awful as the present, when the country is threatened by an implacable and unprincipled enemy, it is of the last importance that the civic chair should be filled by a person in whom the greatest confidence can be placed". Silvester ominously warned Perring that "The keys of the Metropolis are placed in your hands, at the moment when the enemy are at the gates". The ball held later that day at Guildhall was opened with a minuet danced by Perring's eldest daughter and the Spanish Ambassador. The Napoleonic wars and the threat of a French invasion had led to coastal batteries being built as fortifications along the south coast of England in the summer of 1803. Perring was furious to find that a battery had been built on land that he owned at the mouth of the River Yealm in Devon, and wrote to the Secretary of War, Lord Hobart. Perring was eventually pacified by many letters from John Graves Simcoe, who was in charge of the construction of the defences. With the threat of invasion by the French still present, Perring presented the colours of the Corporation of London to the ten regiments of the London Loyal Infantry who assembled at Blackheath on 18 May 1804. Perring was accompanied on the grand procession to Blackheath by the Earl of Harrington, Earl Amherst and Prince Frederick, Duke of York.

Passage: He was born John Miller in County Clare, Ireland. His father was John Miller and his mother, John's wife, Anne née Browne. He was educated at Dalston School and Eton College before joining the British Army in 1760 as a cornet. He was on active service in the Battle of Emsdorf and at Belleisle, France in 1761, before retiring from the army in 1763. He was admitted to study at the Middle Temple in 1765, though does not seem to have made any progress with his legal studies. He also studied at Trinity Hall, Cambridge, though he did not graduate. In August 1765 he married Anna née Riggs (1741–1781), adding her name to his own. They had a son and a daughter. In July 1762 he inherited his family estates; they were worth little, but his wife brought substantial wealth to the marriage, enabling him to build a prestigious house at Batheaston, Somerset. The couple there held a fortnightly literary salon along with competitions and prizes. The prizes were drawn from an ornately decorated Roman vase and the affair was mocked as Lady Miller's Vase, though that did not dissuade distinguished contributions from the like of David Garrick and Christopher Anstey. In 1778 he was created a Baronet, of Ballicasey in the County of Clare. Anna died on 24 June 1781; on 9 September 1795 he married Jane née Sell, widow of Sir Thomas Davenport. He was elected Member of Parliament for Newport, Cornwall in 1784.
