How is it known that the 'invasion' of Britain was not a reconnaissance in force? Caesar could not have known his potential enemies' strengths and weaknesses.
Shall he be blamed for the storms that scattered his fleet and also prevented supplies from reaching him from Gaul?
Ancient armys depended on foraging and conquest for supplies. D.W. Engels in his "Alexander the Great and the Logistics of the Macedonian Army" holds that Alexander's army could only carry three days supplies with them. Logistics, save for roads, had not changed the least for Caesar. Neither Alexander's nor Caesar's supply line backed up to Greece or Rome.
Shall Caesar be blamed for taking whatever opportunities that were presented to him - or to the enthusiasm of his legionaries?
We admit to trade between Britain and Gaul, yet we don't hold that this trade should have been interrupted by a wise commander!
What amazes me to no end, is how, in the bloody white blazes, could such an incompetent scoundrel gain half the empire for Rome, and succeed against the very 'best' men of Rome.!?
