Captain Wilson was something of a legend. He had begun life as a soldier, fighting at the battles of Bunker Hill and Long Island during the American War of Independence. Afterwards, he had enlisted with Sir Eyre Coote's British regiment in Madras, which was deployed against the French in south India. Captured by the French at Cuddapore, Wilson escaped by jumping forty feet from the roof of a prison and swimming the alligator-infested River Coleroon. Recaptured by the troops of the French ally Hyder Ali, he was stripped, chained to another prisoner (who died) and marched 500 miles barefoot before being thrown into Hyder Ali's own gaol at Seringapatam. After being held for twenty-two months, with great iron weights on his arms, Wilson was eventually released. Back in England he published a successful account of his adventures and became a merchant sailor. A stalwart atheist for most of his life, he was converted by an Evangelical sermon he heard at the Orange Street Chapel in Portsmouth.
