Why would the 8th have been in UK for so long?
I can't say for certain but it's possible that they were waiting to be equipped with their tanks and then doing their work up training. In other words they may not have been operationally ready to be deployed.
Where would 'Field' have been.
Field means Field Conditions. One source I have looked at says they were based in
Perham Down Camp on Salisbury Plain. This would have been either tented accommodation or wooden huts. 'Field Conditions' means that the troops are not required to pay for their food and accommodation and that the amenities will be very limited.
Is there anywhere you can recommend I look to find out more about their location and role? War diaries?
There is a regimental history of the 8 RTR in North Africa: Stuart Hamilton
Armoured odyssey : 8th Royal Tank Regiment in the Western Desert 1941-1942, Palestine, Syria, Egypt 1943-1944, Italy 1944-1945. London : Tom Donovan, 1995. ISBN: 1871085306.
The war diaries are scattered around a bit within the National Archive holdings:
WO 169/1408 1 Sep 1939 - 28 Feb 1941
WO 169/1418 1 Apr 1941 - 31 Dec 1941
WO 169/4513 1942
WO 170/9367 1943
WO 170/857 1944 (less Feb)
WO 169/15978 1 Feb 1944 -28 Feb 1944
WO 170/4637 1 Jan 1945 - 30 Sep 1945
WO 166/16615 1Oct 1945 - 31 Dec 1945
Where did they go in the Middle East initially? (I think they ended up at Tobruk).
It seems they first went to 4 Armoured Brigade which was in support of
4th Indian Infantry Division and were deployed to Syria and Lebanon. They were equipped with
Valentine infantry tanks, which as their name suggests were intended to fight alongside the Infantry so were more lightly armoured than main battle tanks. They then returned to North Africa and, still equipped with Valentines, took part in
Operation Crusader in November and December 1941. In mid 1943 8 RTR had its tanks taken away and went to form part of
No 36 Beach Brick and sent to Palestine to prepare for the assault landing on Rhodes. This operation was later cancelled and the men of 8 RTR were re-equipped with tanks and deployed back to the UK in readiness for D Day.
Added: Having just checked Bill's earlier record sheet, since he was taken as a POW in 1942 the last couple of sentences are irrelevant to his story.
