Solid coverage, although without Berlin
I like Christopher Duffy's other work, which focuses on the 18th century, so he covers similar terrain 200 years later. Solid piece, drawing heavily on memoirs of participants, but no major archival revelations from the recently collapsed Soviet Union (he wrote this in 1992). Curiously to me, he left out the Battle of Berlin. I assume to give the run-up more attention in its own right. Solid piece of work by a competent military historian.
