One problem with written records and orders is they are a snapshot of what was in theory to take place at a given time. Without analysis of documents issued following that time and a study of the physical evidence including photographs, you won't know if a given set of orders were followed or the plan was revised or abandoned completely by later orders. Look at Army Council Instructions as an example of ever changing procedures to normal documented practices. And even then you can’t rely exclusively on the documents since the units may not have all received them or in some cases didn’t follow them for various other reasons.

Overall a tough forensic exercise.
