Extract from : Jan Wagenaar, Vaderlandsche historie, vervattende de geschiedenissen der nu Vereenigde Nederlanden, inzonderheid die van Holland (...), 21 delen. Amsterdam, Isaak Tirion, 1749-59.biography of Menno, Baron van Coehoorn (March 1641 - 17 March 1704) who was a Dutch soldier and engineer, regarded as one of the most significant figures in Dutch military history. In an era when siege warfare dominated military campaigns, he and his French counterpart Vauban were the acknowledged experts in designing, taking and defending fortifications.Both had their advocates; Vauban's maxim of 'more powder, less blood' also took longer, an important consideration when most military deaths occurred from disease. He is also viewed as more innovative in the design and extent of his fortifications, which included ports, waterways, roads and even town layouts. However, unlike Vauban, Van Coehoorn had limited financial resources. He showed great skill in maximising these, while adapting to the specific challenges posed by the flat terrain in the Netherlands. Some of his water defences and designs were still being used in the 1950s (wikipedia).
