Yes,... this is one of a number of (fairly) unique insights that Esdaile develops. And, it will be important to remember that there are a number of important shifts in analysis and perspective between, say, Esdaile, C (1988) War and Politics in Spain, 1808-1814, The Historical Journal, Vol. 31, No. 2 (Jun., 1988), pp. 295-317; Esdaile, C (2002) The Peninsular War: A New history; and Esdaile, C (2004) Fighting Napoleon: Guerrillas, Bandits and Adventures in Spain 1808-1814
Thinking about some of the points argued in the first review, by Tone, I think I'd like to have seen this particular debate developed in some detail.
Best wishes
