From October 30 to November 8, 2020, a large-scale battle took place as both sides in the Second Nagorno-Karabakh War fought for control of the city of Shusha. A year later, John Spencer traveled to Nagorno-Karabakh to study the war and the details of the battle—from the unique qualities of the urban and surrounding terrain to the tactics of both the defenders and attackers. In this episode, he shares a short lecture he delivered based on his research during that visit.
