Any good anagrams for perpendicular fortification?

Owes its origin to the Marquis de Montalembert, a distinguished French general, who published his works upon the subject in 1776. Vauban had, it was admitted, rendered the art of attack superior to that of defense. Montalembert strove to reverse this relation, and in his endeavors, rejected entirely the bastion system of the older engineers. Instead of the occasional bastions, with intervening curtains, with which they surrounded their enceinte, he broke the whole polygon into salient and re-entering angles, the latter being generally at right angles. Before the connected redans thus formed were counterguards of low elevation and ravelins, to which the approaches were through casemated caponnieres. In the salient angle of each redan he built a brick tower, 40 feet in diameter, twelve-sided, and four stories high. The second and third tiers were built for heavy guns, and the upper loop-holed for musketry. In the centre of the tower was a circular reduit, intended as a last refuge for the garrison. Montalembert maintained that from these towers every possible approach could be commanded, which to a great extent is true; but it must be also remembered that the greater space a gun commands, by so much the more is it raised above the plain, and rendered visible. These towers would have little chance against the rifled ordnance of the present day. Montalembert’s system was violently attacked by the French engineers, but Carnot subsequently adopted it, with some modifications, and it enters largely into the modern German defensive works. The system has never, however, found favor with British engineers.
