The third and the last campaign by Algirdas was organized in summer 1372. This time Dmitry Donskoy marched with his army to meet the invaders and the Lithuanian army was stopped near Lyubutsk, a fort on the Oka River northeast of Tula. Lithuanian vanguard troops were defeated and had to retreat. The two armies were separated by a steep ravine which was not suitable landscape for combat. After a period of standoff, the Treaty of Lyubutsk was concluded. Algirdas agreed to abandon the plans of promoting Mikhail thus ending Lithuania's assistance to Tver.
