Note 18 — Chapter VII · THE PLAIN OF WEST FLANDERS—YPRES
Reading edition
The evolution of Ypres from a feudal tower on an island until it became a great fortress can be traced in a very interesting volume of maps and plans published by M. Vereecke in 1858, as a supplement to his Histoire Militaire d'Ypres. It shows the first defensive works, those erected by Vauban, the state of the fortifications between 1794 and 1814, and what the English engineers did in 1815.
