regarding the hype :
At Friedland, half of Senarmont's cannoneers were down before the battle ended.
Swords, p. 259
Senarmont gives other figures in his report :
Pertes : 1 officier tuÚ, 3 blessÚ
10 canoniers tues, 42 blessÚs
(this out of 30 gun teams serving 30 guns)
Interestingly 2516 "cartridges" (cartouches) were fired, 368 being cannon balles.
Did the French carry such a load of canister with them?
Next, there the bulk of the cannons were 6 pound guns, I would be interested about the make of them, French - Austrian - maybe Dr. Stephen Summerfield or Paul Dawson know more about this.
