I'm watching a show on Richard the Lionheart tonight, and they stated that it took his army 2 months to march from Jaffa to Jerusalem. 40 miles, 2 months! I know that the Union Army in the ACW was making up to 16 miles a day by the end of the war, Richard's speed was abysmal, even granted that the Union Army had far better logistics. Certainly the Romans could have made it faster. My limited knowledge of the intervening terrain from wargaming indicates no serious natural obstacles or difficult terrain from the coast to Jerusalem....so can anyone explain the poor march speed?
