<p> London Borough of Barking and Dagenham Local Studies Library Information Sheet No. 37 CAPTAIN JOHN PERRY, R.N. </p><p>John Perry was born in Gloucestershire in 1670. He joined the Royal Navy as a teenager, becoming a lieutenant in April 1689. Scarcely a year later, he lost his right arm during a battle with a French privateer (a privately owned ship engaged by the French government). He had remained on duty at his post leaving his wound untreated for too long and the arm could not be saved. Perry spent 1690-1 building a dry dock for large ships in Portsmouth Dockyard. This demanded good engineering skills and Perry designed a technically proficient sluice gate as well as a powerful engine to pump water out of the dock. As a result, he was promoted to captain and placed in charge of a fireship in 1692. However, returning from a year in the West Indies, his ship and that of his superior officer, were attacked off Ireland by two French privateers. This time he was forced to surrender and, in keeping with practice at the time, on his return to England was court martialled for the loss of his ship. Found guilty of failing in his duty, he was sentenced to 10 years’ imprisonment. Perry began his sentence in the Marshalsea Prison in Southwark, but successfully petitioned the Board of Admiralty setting out the justification for his surrender, and in June 1697 he was pardoned and acquitted by the Lords Justices. During his stay in prison, he wrote A Regulation for Seamen (1695), in which he put forward his idea for the replacement of impressment (forcing men to serve) with a system of registering men as naval or merchant seamen for a maximum year's paid service followed by immunity from recall. Perry’s career then turned towards hydraulic engineering. His first job was building a dry dock in Flushing, Holland, but in 1698 he was introduced to the Russian ambassador and was offered £300 per year to work in Russia. He started by surveying the line of a canal to be built between the rivers Volga and Don to link the Caspian with the Black Sea; however work was halted by the outbreak of war between Russia and Sweden. Perry’s next two projects centred on the river Voronezh in south-west Russia, a tributary of the river Don. In 1702-1703 he built a dam across it with a lock which enabled warships to be floated onto the bank for reconditioning. Over the next two years, 1704-05, he constructed another lock further upstream allowing larger ships to navigate into the Don. Perry's salary and expenses had been unpaid for some time </p><p>Please turn over…… but, in 1712, the response to his petition for payment was unacceptable threats and he considered it wise to leave Russia under the protection of the British ambassador. Perry published The State of Russia, under the Present Czar, in 1716. It was an influential account and was widely read running to several editions. Even today it is of great interest as it provides an observation on Tsar Peter the Great's attempts to reform and westernise Russia. Back in England, Perry was contracted to stop the breach in the river wall at Dagenham. A large gap in the flood defences allowed the river Thames, with each tide, to scour out soil from Dagenham marshes. This had created a mud-bank in the middle of the river which was causing a hazard to shipping and trade. Perry built strong sluices and designed dovetailed timber piles to withstand the tremendous pressure of the water at high tide. In total, three dams were built, the last one standing firm against the tide. Gradually, over time, Perry reinforced the embankment which was described as being 5-6m broad, formed of vertical piles and horizontal boarding, and filled with chalk to prevent the foot of the future embankment from spreading. Some 300 men were employed in stopping the breach and it took five years to accomplish. It was completed on 18 June 1719. Following this success, between 1716 and 1724, Perry spent time in Rye, Dover and Dublin advising and designing harbour improvements and in 1727 he was paid for his plans to make the river Ouse in Yorkshire navigable as far as York. In 1729 he settled in Spalding, Lincolnshire, where he acted as engineer to the Adventurers of Deeping Fen and spent time drawing up proposals for the drainage of the fens. He never married and died in 1733, aged 63. He is buried in Spalding parish church.</p><p>John Perry Primary School and John Perry Children’s Centre in Dagenham are named after him.
