Having myself lived the seat, as a child, I have studied the issue. Harrison Salisbury wrote a classic that made known the human aspects: suffering, famine, courage of the inhabitants. David Glantz adds another key dimension: the description of the seat from the perspective of military operations. It is precise, almost dry (the author is a colonel in the US Army and military historian emeritus!), But very enlightening for those interested in the siege of that city héroïque.A recommend without hesitation.
