Judging by the number of replies to this post, this is a popular subject so here is a very short extract from my dad's diary about the RASC ...
What lay ahead of us, nobody knew, but we were most surprised to learn that we were going by road back to Egypt, [From Tunisia, after the battle of Wadi Akarit] a journey of about two thousand miles taken in easy stages to minimise wear and tear on the vehicles, especially for the benefit of those conscientious chaps of the Royal Army Service Corps (RASC), whom I don't believe ever received the credit they deserved for the demanding work they did during the war years.
