How nice that the stats of medieval military dung deposition and disposal have captured our collective interest! I have an apology to make. My memory of the stats given in the programme BBC 1066: A Year to Conquer England - Series 1: Episode 2 was at fault. I rewatched the appropriate moments from around 28-32 mins into the programme:
http://www.bbc.co.uk/iplayer/episode/b08hyhm7/1066-a-year-to-conquer-england-series-1-episode-2Like many BBC documentaries, based on good research and offering a summarised narrative of the accepted academic canon associated with the subject, the stats given in this version of history were:
No of ships (debated) ranges from 777 to over 1000
Army size estimated at 14,000 plus non combatant staff and camp followers
Bread being the staple (70% of daily intake) there were some 14 Tonnes of flour used per day for 6000 loaves each feeding 5 people
The cavalry had around 3,000 horses
The time interval discussed was not daily, I am sorry I got that wrong. Over the 2-3 week encampment awaiting fair weather to cross the channel, Williams army produced an estimated 2500 tonnes of animal and 450 tonnes of human waste and this was shipped out in 5000 carts
in total not daily as I incorrectly opined
This makes it between 250 and 350 carts/day with a cart load being, by simple arithmetic, 600kg (1320lb).
Gentlemen, you were right that the cartage estimate I reported was well in excess for the time interval (day) given. I was adrift by a factor of 15-20.
Please accept my humble and unalloyed obeisance, and revel mightily in your astute observations of that cardinal error.
....even though not one of you made any attempt actually to estimate how much was in a cart or what was the output of a man or horse to support your opinions!
Sorry, had to get a retaliatory dig in there, couldn't resist after all that apologising!
