The siege of Mariupol stands as the defining military anomaly of the Russian invasion of Ukraine. What the Kremlin planned as a rapid conquest of a strategic port city devolved into a grinding 86 day catastrophe for the Russian military. The battle forced a collection of outnumbered and outgunned Ukrainian units to stand against the full weight of Moscow’s professional army.
The defense of Mariupol and the Azovstal steel plant proved to be the undoing of Vladimir Putin’s initial war strategy. By holding out for months against overwhelming odds, a mix of the Azov Regiment and local volunteers shattered the combat effectiveness of Russia’s elite formations. This delay allowed Ukraine to mobilize, secure Western aid, and prepare the defenses that eventually saved Kyiv.
Historian Christopher Lawrence and war correspondent Stefan Korshak provide the definitive account of this stand in their book The Siege of Mariupol. As the President of The Dupuy Institute, Lawrence brings deep quantitative analysis to the battle, while Korshak offers the perspective of a veteran observer of the Donbas front.
Their combined research reveals how amateur soldiers utilized urban terrain to fight a superpower to a bloody standstill. The story of Mariupol is not just one of heroism but a case study in the failure of modern Russian military doctrine.
