discontinue warship construction; for much poorer Friesland this situation would basically last well into the second half of the 18th century. As a result, soon after 1715 Friesland was unable to equip even a single larger vessel. To end this situation, between 1728 and 1730 the English shipwright Thomas Davis in Harlingen built the Prins Friso of 52 cannon, to provide the admiralty with a flagship. This was the only major warship constructed in Friesland between 1700 and 1758. In 1740 the frigate Termeer was purchased from the Admiralty of Amsterdam and renamed the Friesland. In the second half of the 18th century a minor Dutch naval renaissance took place with modern warships being built in an attempt to counter growing British naval dominance. Friesland also embarked on a small construction programme. In 1758 Charles Bentham built the Prins Willem (36 cannon), in 1760 wharf master Willem Lodewijk van Genth built the Princesse Maria Louisa (54 cannon), and in 1769 the d'Eendracht (24 cannon) was built. After 1778 production accelerated and fourteen vessels were under construction between that year and 1789, though two of these would remain unfinished. The Harlingen Era The Harlingen period encompassed both the apex and the lowest point of Frisian sea power. At the height of the admiralty, Harlingen had four wharfs. Dozens of warships were launched. This period produced naval heroes such as Tjerk Hiddes de Vries and Auke Stellingwerf, both fatally wounded during naval service—under Dutch conventions, being killed in battle was the mark of a real naval hero. Under the command of Tjerk Hiddes de Vries, during the Second Anglo-Dutch War, the Frisian Admiralty's fleet was at its largest, with no less than forty vessels, large and small. The Frisian Admiralty in this time also profited from the sale of seized goods and ships. For example, during the Four Days Battle on June 13, 1665, the Nagelboom, a VOC ship taken the previous year by the English during the Battle of Lowestoft, was recaptured by the Frisians. As it was their prize it was also their legal possession, no longer that of the VOC. In an advertisement in the Haerlemse Courant a year later the same ship came up for sale: The council members of the Frisian Admiralty present to be publicly sold to the highest bidder a capital and distinguished Warship named the Nagelboom, captured by Vice-Admiral Coenders in the latest Battle
