Somme WW1 - area 574

[Michael Dobbs]

I have received the following enquiry from Canada

[color=maroon]Hello. I am researching a soldier from WW1 for a course at Western University. I know that this soldier used the field post office D6 that was the Somme area. I have also learned that he was operational in area 574. Do you know where that area is?[/color]

Can anyone help please?

Thanks, Mike  :)
