In contrast to Jomini, Clausewitz largely dismissed the value of military intelligence: "Many intelligence reports in war are contradictory; even more are false, and most are uncertain. . . . In short, most intelligence is false." His conclusions were influenced by his personal experiences in the Prussian Army, which was often in an intelligence fog due to the superior abilities of Napoleon's system.

Mao read Clausewitz's ''On War'' in 1938 and organized a seminar on Clausewitz as part of the educational program for the Party leadership in Yan'an. Thus the "Clausewitzian" content in many of Mao's writings is not merely secondhand knowledge, via Lenin (as many have supposed), but reflects Mao's own in-depth study.
