Some 20,000 French civilians were killed in the two-and-a-half months from D-Day, 3,000 of them during the actual landings.

"It was rather a shock to find we were not welcomed ecstatically as liberators by the local people, as we were told we should be... They saw us as bringers of destruction and pain," Mr Roker wrote in his diary.
Another soldier, Ivor Astley of the 43rd Wessex Infantry, described the locals as "sullen and silent... If we expected a welcome, we certainly failed to find it."

It is not as if the devastation wrought by the Allies is not known - it is just that it tends not to get talked about.
And yet for many families who lived through the war, it was the arrival and passage of British and American forces that was by far the most harrowing experience.

In his book, Mr Hitchcock raises another issue that rarely features in euphoric folk-memories of liberation: Allied looting, and worse.
"The theft and looting of Normandy households and farmsteads by liberating soldiers began on June 6 and never stopped during the entire summer," he writes.

One woman - from the town of Colombieres - is quoted as saying that "the enthusiasm for the liberators is diminishing. They are looting... everything, and going into houses everywhere on the pretext of looking for Germans."

Even more feared, of course, was the crime of rape - and here too the true picture has arguably been expunged from popular memory.

According to American historian J Robert Lilly, there were around 3,500 rapes by American servicemen in France between June 1944 and the end of the war.
