Aldington was the stronghold of The Aldington Gang, a band of smugglers roaming the Romney Marshes and shores of Kent. The gang's leaders, made the local inn, The Walnut Tree Inn, their headquarters and drop for their contraband. The Inn was often used when they waited for others of their group to bring in goods from across the Marshes. High up on the southern side of the inn is a small window through which the gang would shine a signal light to their partners up on Aldington Knoll when the way was clear for them.
They were probably the last 'major' gang that existed in Kent and it is believed that they were known as The Blues from the colour of the clothing that they wore or from blue flares used for signalling.
The gang was probably founded in or around 1817, as gang-based smuggling returned, but the first mention of the Aldington Gang was in November 1820, after the men had returned home from the Napoleonic Wars and found little to do to make any money. It is believed that they were active well before this date and were responsible for incidents in Deal, St. Margaret's Bay, north of Dover. The gang carried out a landing near Sandgate with 250 men taking part, unloading a galley laden with spirits, tobacco and salt that had been rowed across the Channel from Boulogne and pulled up onto the shingle beach. Three groups of smugglers had gathered: one to unload and transport the cargo and two groups of "Batmen", to protect the first. They were spotted by a few local blockade men, as the main blockade force had been lured away by the smugglers. "Batmen" stood guard when a run was taking place to fight off anyone who tried to interfere; they gained their name from the long clubs, or ‘bats’ they carried. Some smugglers used guns, although the shooting of the Revenue officer often roused the authorities to step up their efforts against smuggling.
In February 1821 the Battle of Brookland took place between the Customs and Excise men and the Aldington Gang. The smugglers had sent 250 men down to the coast between Camber and Dungeness but the party was seen by the Watch House at Camber and a fight took place over Walland Marsh. Although the Gang successfully completed the unloading of the goods, they were harried right across the Marshes until they reached Brookland, where the Gang turned on the blockade force. Five men were killed in the fighting and there were more than twenty wounded. Their leader at that time was Cephas Quested who, in the confusion of the Battle, turned to a man close by him, handed him a musket and instructed him to "blow an Officer's brains out." Unfortunately for Quested, in the confusion of the fight and being somewhat intoxicated, the man that he had turned to was a Midshipman of the blockade force, who immediately turned the gun on Quested and arrested him. After being sentenced, Quested was taken to Newgate and hanged for his activities on 4 July 1821.
