In the Writer's Muses Novel:
Colonel Thomas Rainsborough (1610 – 30 October 1648), was a prominent figure in the English Civil War, and was the leading spokesman of the Levellers in the Putney Debates.
Born the son of William Rainsborough, a captain and Vice-Admiral in the British Royal Navy, and Ambassador to Morocco. The elder Rainsborough was offered a baronetcy for his efforrts in ending white slavery in North Africa, he decined the offer.
Before the English Civil War, Thomas and his brother, William, were both involved in an expedition to the Puritan Providence Island colony, off the coast of Nicaragua. Thomas commanded the Swallow and other English naval vessels in the first civil war. By May 1645, he was a colonel in the New Model Army, taking an active part in the battles at Naseby and at Bristol. Later that year, he captured the symbolic stronghold of Berkeley Castle. In 1646, he helped conclude the Siege of Worcester.
In January 1647, Rainsborough became a member of parliament for Droitwich. He was the highest ranking supporter of the Levellers in the New Model Army and one of the speakers for the Leveller side in the Putney Debates (July 1647), where he opposed any deal with the King.
In early 1648, he was due to return to the Navy as a Vice-Admiral, however, because his Leveller sympathies were fairly unpopular with some officers, a mutiny ensued. Thomas Rainsborough was returned to Army service.
In October, he was sent by his commander, Sir Thomas Fairfax, to the siege at Pontefract Castle, where he was killed by four Royalists during a bungled kidnap attempt. His funeral was the occasion for a large Leveller-led demonstration in London, with thousands of mourners wearing the Levellers' ribbons of sea-green and bunches of rosemary for remembrance in their hats. After his death, his brother, William Rainsborowe continued in the Leveller (and Ranter) cause.
