The capitulation at the Vlieter was a national humiliation - and a strategic lesson. Twelve years later, when Napoleon stood on the dunes of Den Helder and looked across the Marsdiep at Texel, he absorbed the lesson and gave the order. A naval base would be built here. A ring of fortifications would protect it. Six million francs would pay for the works. The result, expanded by every Dutch government for the next century, became the Stelling Den Helder - and earned the nickname 'the Gibraltar of the North'.

The Battle of Hampton Roads in March 1862, where the USS Monitor and the CSS Virginia fought to a smoking draw, ended the era of wooden warships in a single day.

Only Fort Harssens's guns posed any real threat to a modern battleship. Through the interwar years th...
