Footage recorded by a Ukrainian forward observer in 2015, shows an intense Russian-backed DPR artillery bombardment on an urban Debaltseve neighborhood during a separatist offensive to take the city.

The audio suggests that the city is initially on the receiving end of a rocket cluster munition strike as several rapid explosions rattle the city. Following the cluster strike, artillery can be heard ripping through the air overhead and crashing with point detonating high explosive munitions.

Russian proxy forces of the DPR encircled the city and relentlessly dropped artillery and rockets for over a month. Eventually the Ukrainian troops ran out of supplies and ammunition and thousands retreated while others were trapped with no escape.
