Like many, I find Dday and onwards fascinating. However so much is going on that the overall progress of the advance - or lack of it at times, is difficult to take in.
This excellent map shows the advance of the main units of all the allied armies, with the relevant dates shown. One can easily see who the adjacent units were and where hold ups occured.
My only major criticisms are
the small scale - ok I accept this is difficult to do on a standard map size,
the dominating weak single colour used to show movements.
That said this is the best single map I have seen of the Normandy campaign and is recommended for use of anyone interested,students of all levels and abilities, re enactors etc. should find information of interest.
