Have been doing some pre-battle "bookkeeping" for the ongoing campaign......
One of the things about running a campaign (as opposed to gaming one-off fights) is the "shock" of how QUICKLY your army gets whittled away - not so much in battle, which one expects, but with the allocating of troops to protect lines of communication, garrisoning salient points and the drip-drip-drip of desertions (and SO far I've managed to keep my guys fed & watered.....).

Apropos; I was looking through the pre-battle "Order of Battle" for Burgoyne's army at Saratoga the other week (like you do..) and was (yet again) stuck by the comparison with the "paper strength" of his regiments and the réalité of the "effective strength"... These ranged from an average of just over half the paper strength to just over a quarter (!!!) in one case....
Meanwhile, back on the map....

Sepporis has fallen after a only week's seige (Yielded on terms. We can still afford to be generous). The next week is taken up with:
A cavalry probe towards (hostile, fortified) Arbela, which comes face
to face with a blocking force - and swiftly comes scurrying home without
engaging (Clever boys..).
Little Garis turning out to be friendly - but the settlement will need a garrison (no pun intended) to keep it safe from raids from Arbela.
More probing.. On the road to (as it turn out, hostile, fortified) Tiberias the patrol of horse are ambushed... Except where...? The nearer one gets, the flatter the country.... Help me Mr. Google....
There is an indecisive skirmish (the enemy have no horse and the ground is a bit "Meh"...). The above is followed by a day or two of Strategic thinking (Council of War), loss assessment, redistribution of garrisons etc....
A decision has been reached that Tiberias - with its direct road connections to garrisoned Scythopolis and Garis, plus the threat it poses to friendly Pella, Gadera and Hippias - HAS to be the next target.
This being so, a plan to march a legion and supports force via Ptolemais to Bersabe to push into Galilee from the north, in concert with the two legion push from the south, in order to speed things along, has been put on hold....
One of the frustrations of campaigning... I turned my back for a moment while sorting a logistic issue and having a "Council of War" and raiders from the "soon to be besieged" Tiberias raided friendly Pella. THEN, once I got them moving, my columns ran into bad weather before they got any further in closing down this danger point... Frustrating, yes; but "real".... Chess this ain't..
The army moves. besieging Tiberias (another 8 days lost) then on to Tarichaeae (another nine days). Losses are minimal but keeping my army together is eating up the weeks. Having taken Tiberias and Tarichaeae the army moves to Beersabe, which surrendered after three days.
Here is the balance problem: a large army can scare the enemy into surrender or subdue a town by sheer presence/numbers in a siege situation. However, this will always take at least a week (plus clear up). I can deal with more towns at a time by splitting my force, but each individual siege will likely take longer, use more supplies, leave those columns more vulnerable to ambush and could result in losses in manpower I cannot afford... Hmmm.....

Titus and the Vth have been left at Beesave. Meanwhile, Vespasian and the rest of the army retrace their steps, to Tarichaeae, then move to deal with hostile, fortified Arbela. An ambush is triggered.....
Again, I get Google Maps up and running. The short distances involved flummox me once more...The approach from the Sea of G. is flatish - until it starts rising to the mounts, where there is a suitable looking "ambush me" gully..

"Arbela" seems to cover the mount itself and possibly the nearby jebel, both of which look riddled with caves, as described/hinted at in some sources, which Josephus seemingly protected with walls..

Given the small distances involved, assuming I beat off the ambush, this might turn into an interesting a "follow-up and assault" on the table, rather than a siege. Looks have to dug out me old cork bits for this one...

Meanwhile: From the Annual Annals of Crun the Elder:
"And Vespasian, with all his arméd might, did march from Tarichaeae even unto Arbela, and on first sighting this fell hold of his enemies gathered unto himself his Legates and spoke unto them, saying "What the frick..??!! I was expecting a town, not a bloody rock..."
Honestly, sometimes being ambushed en route is a positive relief...
