As to fortifications General Patton observed’’No hole in the ground, anywhere, has ever been successfully defended’’.

I do hope the good general was joking. The successful defenses of fortifications are FAR too numerous to list.

To give just one example, over a thousand years Constantinople was beseiged dozens, possibly 100, times. It was taken only twice.

With Patton the truth lies somewhere in between. But as warfare has evolved forts have become obsolete. Mobility is what warfare now is all about. As I pointed out, in the modern era one need only to look at the Maginot Line(and ‘’Maginot Thinking’’), Hitlers Atlantic Wall and the Siegfried Line to see the futility of fixed fortifications. As stout as any fort is/was it can just as quickly become a tomb.
