Hastings also points out that the Germans had vehicles that could not be penetrated by rifle fire and that alone gave them an edge.
Thanks, Juha, your reply interrupted my laughing!! Hastings is clearly a genius
The intelligence gathered by 21 Army Group and that passed on to 1 Airborne Div was IMHO pretty accurate. The remants of II SS Pz Kps could well be described as about a brigade group with a few tanks. A very rough timeline suggests that armour support for the Germans in Arnhem arrived in something like the following order (by memory so please forgive some mistakes):
17 Sep - armoured cars of 9 SS recce, couple of tank destroyers, perhaps a couple of AA tanks
18 Sep - about a dozen Pz III and Pz IV from training company from Ruhr area.
18 Sep - about a dozen old French tanks from the West.
19 Sep - about a dozen StuGs from Assault Bde - diverted from en route to Aachen.
19 Sep - end of day, Tiger company 'Hummel'
20 Sep - Tiger II batallion (may have been 21 Sep - sorry I can't remember)
The problem for the airborne troops, therefore, until probably the 20 Sep at least, was not the number and quality of the German armour but that they were trying to attack into the face of it. When the tables were turned and the Germans tried to use their armour in an offensive role in the built up areas that the British held they suffered considerable casualties. If the British had been settled down into defensive positions by say midday 18 Sep, then at least until late on 20 Sep and perhaps later, they should have been able to handle the German armour to much greater affect.
For example, on 19 Sep, 11 Para were overrun by a few StuGs as they were in an offensive posture, their anti-tank guns were not deployed and, in one case, the company PIAT was on the back of a jeep that the padre had used to evacuate casualties.
Urquhart admits that by the time of Arnhem, his division was bored and desperate to get into action. IMHO even if they had been told the brigade group consisted of SS troops it would not have made much difference to their attitude or their plans.
