One of the great thrills of producing the reference on the 1815 campaign is the impact it has made to other authors and enthusiasts.
Diego Mané (www.planete-napoleon.com) has provided much errata as well as a detailed analysis and commentary of the 1st Corps Diary found in the reference.
It is definitely worth your time!
1815-Journal du I° Corps commenté-v2
His commentary on the series, including noting errors in transcription or inconsistencies with other sources, is also very useful.

Diego is an expert with detailed knowledge of the order of battle for the campaign, and thus was able to clarify numerous transcription errors and unknowns.
