83rd Infantry Division, 5 July, 2400

Here’s a second overlay for July 5th at 2400.  This one looks to have been made at the divisional level since it includes something from all three regiments plus some artillery and an engineering unit.  You will notice right off that there is something wrong with this overlay.  Some of the symbols are not complete, for one thing.  That is because the declassification sticker was attached to the overlay exactly over where some of these symbols are; big help. But also this was one large overlay that had been folded in half all these years and had disintegrated along the fold.

This created the second problem.  Now the two reference points were separated one from the other on separate sheets.  If I had thought getting the geo-referencing was tricky with two reference points, then I had a real problem trying to understand how to do it with one on each of two sheets.  In the end, besides the triangulation, which in itself could not resolve the problem of how to position one sheet in relation to the other, I used what I knew should be the distances on the overlay since it was traced over a 1:25000 map.  I have avoided doing this because the overlays are a mess in general with no straight edges and badly drawn reference points, wrinkled and most often, not very well scanned.  But this time there was no other way and I think we came pretty close.  There is still the problem of properly orienting the two sheets to each other, but from the final result it seems to be very close indeed. You’ll notice a bit of an over run on the right-hand side, while the second reference point of off the map to the left because I didn’t want to use up space just to include it.
