Fighting between Ukrainian and Polish forces was concentrated around the declared Ukrainian capital of Lviv and the approaches to that city. In Lviv, the Ukrainian forces were opposed by local self-defence units formed mostly of World War I veterans, students and children. However, skillful command, good tactics and high morale allowed Poles to resist the badly planned Ukrainian attacks. In addition, the Poles were able to skillfully buy time and wait for reinforcements through the arrangement of cease-fires with the Ukrainians. While Poles could count on widespread support from the civilian population, the Ukrainian side was largely dependent on help from outside the city. Other uprisings against Ukrainian rule erupted in Drohobych, Przemyśl, Sambir and Jarosław. In Przemyśl, local Ukrainian soldiers quickly dispersed to their homes and Poles seized the bridges over the River San and the railroad to Lviv, enabling the Polish forces in that city to obtain significant reinforcements.
