Normandy Grid Ref help needed.

Hi Guy
I am reading some Morning reports from a Company with the American 9th Inf Reg and I am trying to locate the field from the Soldiers grid reference.
I wonder if anyone could please help ma as I has tries everything.
The Morning report states that their company was at Litteau France 63759......also mentioned is 625649.
Both locations are from June 1944.
Please could someone point me in the right direction of if I can find with a modern Map or need to Purchase a WW2 map.
thanks
Michael

 

Notes on the "Modified British System" used on the European Theatre of Operations during the WWII

It is French Lambert Zone 1, Grid vT and the complete six digit reference you gave 625649 results in 49.138210,-0.918761 - Map of Cities in 49.138210,-0.918761 - MapQuest

The first reference is incomplete, so is more difficult to determine. If you add a zero at the end to derive a six figure grid you get

Google Maps

 

You can download 1:100,000 maps with 1944 grids here France AMS Topographic Maps - Perry-Castañeda Map Collection - UT Library Online You need St Lo -Valognes

The town of Littau is in grid square 6366

 

Thank you so much for taking the time to reply.How did you covert this over?I am currently researching the American 9th Infantry Reg and have a number of different fields to locate.I have one very important one to find and I was going to try to find it tomorrow.Could you try 6483-6172 this is how the soldiers have put it in the morning report.

Thank you for this Sheldrake.
This is fantastic but I need to be more accurate as I am looking for a field.Is there site with a better scale.I did find the map you suggested but I can not get so close.

It took a while but I got the system.
Thank you so much for this.

There is a 1:50,000 map covering the area on the British Library Website
France 1:50,000 , Series GSGS 4250, St. Lo

I don't know where to find 1:25,000 maps.

 

Just follow the directions in the website. The trick is figuring out which letter grid you need to use. 6483-6172 likely described a linear position. vT6483 is:

49.301407,-0.908906 - Map of Cities in 49.301407,-0.908906 - MapQuest

vT6172 is:

49.201413,-0.943535 - Map of Cities in 49.201413,-0.943535 - MapQuest

 

Thank you RichT090,I've managed so work it out now.Spent a few hour last night converting some of the MR over and it's very interesting.
You have given me a great jump start to my research so really thank you for taking time on this for me.Have a good week-end
Michael.
