I know exactly how far it is from Cairo to Mersa Matruh and from Matruh to Tobruk and from Tobruk to Benghazi and from Benghazi to Agheila and importantly from Agheila to Tripoli and all the other towns, villages and water holes that became significant in the progress of the Desert War. Moreover I fully understand that virtually everything units needed to survive and fight; water, food, ammo and petrol had to be carried by truck. However, distances between supply hubs and end users varied as did the going, the condition of the vehicles and the amount and carrying capacity of the supply echelons.
Well in fairness I said 'underestimate', and I think we have an important data point in that in January 42 13 Corps was simply not adequately supplied. End of. This despite Tobruk being fully operational as a port.
Norm wrote:In regard to my claim that O’Connor could have gone on to Tripoli and your and David’s counter claim that lack of transport or the condition of the transport, or the distances involved, or all three, would have prevented a forward move I would remind you that when the advance was stopped at Agheila the main elements of O’Connor’s forces turned round a drove 1,000 miles back to Cairo. If they could do that then why could they not go on the 450 miles to Tripoli?
Because he didn't have to fight his way back to Cairo, and he was moving back on his supply line, instead of away from it.
Norm wrote:Nor did he have to rely completely on truck borne supplies coming all the way from Matruh. For a start off he did not arrive at Agheila completely devoid of supplies or short of vehicles. Both 7AD and 6AID had enough supplies and vehicles for their immediate needs, the Australians had just captured and taken into their ownership over 700 vehicles at Tobruk, moreover 7AD had just captured an Italian column at Beda Fomm of over 1,000 vehicles many stacked high with food and petrol. Furthermore there was abundant water at Benghazi, Derna, Tobruk, Mersa el Brega and Agheila and, when they advanced, there was a good water source at Sirte all they had to do was drink it fill their water bottles with it and refill their water trucks with it; not difficult.
How long are those vehicles going to last without spares? How long does it take to take them away from those who captured them and distribute them to those who need them (not the same people). The water at all of these places still needs to be supplied over hundreds of miles.
Norm wrote:David please note, Tobruk was opened almost straight away after its capture, moreover within a few days of the Beda Fomm battle the Royal Navy were able to land 2,500 tons of petrol and 3,000 tons of other supplies at Benghazi, this info was taken from Raugh, p 123, but there are loads of sources which confirm supplies were quickly landed at Tobruk, Derna and Benghazi after their capture.
And how much did they need on a daily basis? The Germans in autumn estimated about 600 tons per day for a force that about equalled probably two divisions and was supplied over a similar distance. What were the means of getting the supplies to the forward units? How would increasing the strength of the forward units impact that? It was a 6-day lorry turn-around from Tobruk to Mechili according to the report added below (160km, 100 miles).
Norm wrote: In addition a petrol and ammunition supply point was quickly established at Derna.
Given the characteristics of Derna harbour, that was probably worth the proverbial bucketful of warm spit.

Only submarines, destroyers, motor schooners, and vessels <500 tons could use that harbour.
Norm wrote: Furthermore, the Navy guaranteed to land double the amount of supplies they were already landing at Tobruk if they were needed. The Navy’s view on supply was that although it would not be easy they were confident that they could supply O’Connor’s army of two divisions if he decided to advance on Tripoli.
Double of what number? Again, with the distance from Tobruk to Agheila and then Sirte, that's not the best place. The key question would have been what they could get into Benghazi by sea, and out by land.
Norm wrote:Urmel what relevance has the state of an Indian brigades transport in February 1942 got to do with a possible advance on Tripoli by two divisions in February 1941?
It's a data point.
Norm wrote:It is no use saying the Germans needed just under 5 vehicles per man in autumn 1941.
Why not? Again, it's a data point. That's the about of M.T. they had, and it was not enough.
Norm wrote:Where did this information come from what units were involved did this figure include tanks, motor bikes and support units?

Norm wrote: On what basis is the calculation made that it would have taken 20,000 vehicles to move 8 Army in late 1941 and what relevance does it have to the amount of vehicles required by O’Connor anyway? And again where does this information come from?
It's a simple calculation. It's probably not very relevant.
Norm wrote:And if you all know so much why not tell me how many trucks were in the Middle East before the war broke out? How many arrived per month after the declaration of war? What was the average wastage rate? Which units arrived with vehicles and which without? How many trucks per month came from the US, Canada, South Africa and India? What were the vehicle requirements of an infantry or tank division in the Western Desert in 1940/41/42/43? How many trucks were there in a second or third line transport company and what vehicles did they use 3 ton/5 ton/10 ton?
All good questions. Not that I have the answers.
Here's some information, from 3 CLY War Diary (Cruiser regiment) for October 41 - that's what they went into battle with, I have no idea if that was what they were supposed to have:
Trucks: 93
66 – 3 tonners.
2 – 3 tonner Fitters lorries.
18 – 15 cwt trucks.
4 – 15 cwt Water Trucks.
2 – 8 cwt trucks.
1 – 15 cwt Office truck.
Light vehicles: 9
8 – Utilities
1 W/T van.
2 RGH reported 112 B Vehicles.
So for 22 Armoured Brigade just the three cruiser regiments gets you to 300 trucks, for four cruiser/army tank brigades outside Tobruk you get to 1,200 for the armoured regiments alone.
Central India Horse 114 trucks and lorries, 20 other vehicles.
For a 3-battery regiment I count 82 trucks here, excluding tractors (60 for a 2-battery regiment):
http://nigelef.tripod.com/fdregt41.htm
I have 10x3 bty, 9x 2 bty. 88 trucks for a medium regiment (there were two) Total first line trucks for these would be 1,536.
I am getting close to 3,000 trucks already, without considering the infantry battalions, brigade transport companies, AT-regiments, second line divisional transport and 3rd line transport, and the RAF.
Norm wrote:making ill informed petulant outbursts never will.
Quite right.
Here's some proof that the advance to Beda Fomm was already undertaken on a shoestring, at least in the view of the Quartermaster. Note in particular the 'wondering what to eat the next day', indicating that the captured supplies may not have been very plentiful (and in any case, the POW presumably were fed and watered as well). Unfortunately I lost the record marker on this one, I think it's in WO201.
