Georgian commanders planned to concentrate their forces at the town of Mtskheta, northwest of Tbilisi, and continue fighting on new lines of defense; the fall of the capital, however, had heavily demoralized the Georgian troops, and Mtskheta was abandoned. The army was gradually disintegrating as it continued its retreat westward, offering sometimes fierce but largely unorganized resistance to the advancing Red Army troops. Sporadic fighting continued for several months as the Soviets secured the major cities and towns of eastern Georgia. The Mensheviks entertained hopes of aid from a French naval squadron cruising in the Black Sea off the Georgian coast. On 28 February, the French opened fire on the 31st Rifle Division of the 9th Red Army under V. Chernishev, but did not land troops. The Georgians managed to regain  control of the coastal town of Gagra, but their success was temporary. Soviet forces joined by Abkhaz peasant militias, the Kyaraz, succeeded in taking Gagra on 1 March, New Athos on 3 March, and Sukhumi on 4 March; they then advanced eastward to occupy Zugdidi on 9 March and Poti on 14 March. The Georgians' attempt to hold out near Kutaisi was spoiled by the surprise advance of a Red Army detachment from North Caucasia, which traversed the virtually impenetrable Mamisoni Pass through deep snow drifts, and advanced down the Rioni Valley. After a bloody clash at Surami on 5 March 1921, the 11th Red Army also crossed the Likhi Range into the western part of the country. On 10 March Soviet forces entered Kutaisi, which had been abandoned, the Georgian leadership, army and People's Guard having evacuated to the key Black Sea port city of Batumi in southwest Georgia. Some Georgian forces withdrew into the mountains and continued to fight.
