Calling all armchair generals! Boudica's Last Stand.

By your estimates it would have been impossible for any Roman army to operate in Britain or anywhere else for any length of time.

Nope, im using maths to show the logistical problems of your description of events and why your description is not a believable explanation, as what you describe is logistically improbable. If you dont like your implausible description being pulled apart, then the solution is to only post plausible explanations.

I repeat - If you still do not believe that this is plausible, provide an alternative.

Its not plausible to anyone who can count or understands how armies logisticaly support themseves.

So in fact the timeline is on the generous side. But my intention was to show what is plausible, and I have done so.

If you still do not believe that this is plausible, provide an alternative.

Ok , how about a timeline that adds 10 days to the time reach Rome and then on to the Rhine, its advantage over your time line, is that it does not involve staying awake 24 hours a day and riding every hour of the 24 and does not use an unfinshed function in Orbis.

We are told the Emperor dispatches the legions, so the order to march to Britain come from him. Augustas changed the system to have the same courier take the important dispatch from sender to receiver, and be able to be questioned if there was anyything more the receiver wanted and had a first hand person to ask, so the top ceiling is measuring day and night transfer, which a single courier cannot do as he cannot stay awake 24 hours a day to ride 250klm a day.

Orbis.
"Mean daily travel distances have been set at 12 kilometers per day for ox carts, 20km/day for porters or heavily loaded mules, 30km/day for foot travelers including armies on the march, pack animals with moderate loads, mule carts, and camel caravans,[18] 36km/day for routine private vehicular travel with convenient rest stops, 50km/day for accelerated private vehicular travel, 56km/day for routine travel on horseback, 60km/day for rapid short-term military marches without baggage, 67km/day for fast carriages (state post or private couriers), and 250km/day for continuous horse relays (Scheidel in preparation). Except for the final option, which is primarily meant to provide an absolute speed ceiling for multi-day terrestrial information transfer, these transport options are predicated on movement during daytime. Adjustment for night travel would produce higher rates but would usually be feasible only in the short term.".

So horse relay is an unfinished function and gives the absolute ceiling. Most books ive read on the courier service of Rome give that ceiling at 150klm a day for important dispatch, going same route as orbis is a 24 day journey, 10 days longer than Orbis.
