Very nice, thank you.
I found this comment, on p 300 of Lessons of war as taught by the great masters and others: selected and arranged from the various operations of war by France James Soady. Published by W.H. Allen, 1870. 565 pages, of interest:
“70. The camp at Boulogne, was the first school of the tactics in mass, henceforward destined to be successfully practised on the field of battle, and the war of 1805 gave the first opportunity of bringing them into play.” See:
What do we know of the artilleries part in the ‘school of the tactics’ initiated at the camp at Boulogne? Is Soady saying the camp at Boulogne was the source of Sénarmont’s ideas?
