“Russian forces may attempt to bypass the eastern flank of Ukrainian positions in Velyka Novosilka and intensify pressure on Velyka Novosilka from the south to force Ukrainian Defense Forces units to withdraw from the village, enabling further advancement toward the southwestern edge of Donetsk Oblast,” the Ukrainian Center for Defense Strategies explained.

“Losing the town of Velyka Novosilka will not, in itself, be that much of a disaster, in the grand scheme of things,” Perpetua explained. “It is just one town. It is the fact that Russia is attacking the defensive line from the flank, parallel to the defenses, which is the true disaster.”

If Russian troops can get around the fortifications in Velyka Novosilka, they might be able to duplicate this maneuver in other sectors in the east. Ominously, there probably aren’t many Ukrainian reserves in the area that could staunch the infiltrations.

“The strength of these defenses, and the difficulty of attacking this ground, allowed Ukraine to underman these areas to shift forces to other areas,” Perpetua pointed out. “That's over. Now you need to begin sacrificing other areas to defend here.”
