The Institute for the Study of War’s March 19th update leads off with an exceptionally long and detailed summary, the essence of which is that the war appears to have ground to a stalemate. Here are key excerpts, but it’s worth your while to read the whole thing. The final paragraph is particularly important.
Ukrainian forces have defeated the initial Russian campaign of this war. That campaign aimed to conduct airborne and mechanized operations to seize Kyiv, Kharkiv, Odesa, and other major Ukrainian cities to force a change of government in Ukraine. That campaign has culminated. Russian forces continue to make limited advances in some parts of the theater but are very unlikely to be able to seize their objectives in this way. The doctrinally sound Russian response to this situation would be to end this campaign, accept a possibly lengthy operational pause, develop the plan for a new campaign, build up resources for that new campaign, and launch it when the resources and other conditions are ready. The Russian military has not yet adopted this approach. It is instead continuing to feed small collections of reinforcements into an ongoing effort to keep the current campaign alive. We assess that that effort will fail.
The ultimate fall of Mariupol is increasingly unlikely to free up enough Russian combat power to change the outcome of the initial campaign dramatically. . . . The block-by-block fighting in Mariupol itself is costing the Russian military time, initiative, and combat power. If and when Mariupol ultimately falls the Russian forces now besieging it may not be strong enough to change the course of the campaign dramatically by attacking to the west.
Russian forces in the south appear to be focusing on a drive toward Kryvyi Rih, presumably to isolate and then take Zaporizhiya and Dnipro from the west but are unlikely to secure any of those cities in the coming weeks if at all. . . .
The Russian military continues to commit small groups of reinforcements to localized fighting rather than concentrating them to launch new large-scale operations. . . .
The culmination of the initial Russian campaign is creating conditions of stalemate throughout most of Ukraine. Russian forces are digging in around the periphery of Kyiv and elsewhere, attempting to consolidate political control over areas they currently occupy, resupplying and attempting to reinforce units in static positions, and generally beginning to set conditions to hold in approximately their current forward positions for an indefinite time. . . .
Stalemate will likely be very violent and bloody, especially if it protracts. Stalemate is not armistice or ceasefire. It is a condition in war in which each side conducts offensive operations that do not fundamentally alter the situation. Those operations can be very damaging and cause enormous casualties. The World War I battles of the Somme, Verdun, and Passchendaele were all fought in conditions of stalemate and did not break the stalemate. If the war in Ukraine settles into a stalemate condition Russian forces will continue to bomb and bombard Ukrainian cities, devastating them and killing civilians, even as Ukrainian forces impose losses on Russian attackers and conduct counter-attacks of their own. The Russians could hope to break Ukrainians’ will to continue fighting under such circumstances by demonstrating Kyiv’s inability to expel Russian forces or stop their attacks even if the Russians are demonstrably unable to take Ukraine’s cities. Ukraine’s defeat of the initial Russian campaign may therefore set conditions for a devastating protraction of the conflict and a dangerous new period testing the resolve of Ukraine and the West. Continued and expanded Western support to Ukraine will be vital to seeing Ukraine through that new period. [emphasis added]
