For the last two months, since the beginning of the pro-Russian offensive in late December last year, the Ukrainian army has held the city of Debaltseve. Located on a strategic rail and road junction which effectively split the two separatist republics (LNR and DNR), the city was home to one of the largest Ukrainian Army garrisons deployed across the line of contact established during the first Minsk Agreement. Despite this deployment of between 6000-8000 Ukrainian troops, artillery and armor, the city lay in a very precarious position when fighting resumed. Hemmed in on three sites by towns and cities controlled by the so-called “Novorossiya Armed Forces” (NAF), the Ukrainian garrison was only able to maintain supply through a narrow corridor to the north-west of the city. Following the fall (or complete destruction of) of Donetsk International Airport, the main bulk of the NAF was committed to slowing closing this supply corridor.
