Bousmard is, on the whole, a very able writer, and his works should be found in the library of every military engineer.
Carnot's celebrated treatise was published in 1810.

He was evidently a man of genius, and during his career at the head of the War Department of France, numerous and very important improvements were made in the several branches of the military art, and especially in strategy.

His work on fortification exhibits much originality and genius, but it is doubtful whether it has very much contributed to the improvement of this art.

His ideas have been very severely, and rather unfairly criticised by the English, and particularly by Sir Howard Douglas.
Chasseloup de Laubat early distinguished himself as an engineer of much capacity and talent.

He followed Napoleon in nearly all his campaigns, and conducted many of his sieges.
