In 1919, on 19 June, the decisive second phase of the Battles of Cēsis began. Near Cēsis, the Estonian Army and units of the Northern Latvian Brigade under its operational command, including the 2nd Cēsis Infantry Regiment, faced the Baltic Landeswehr and Germany’s Iron Division, which were subordinated to Andrievs Niedra’s government. This phase of fighting ended with a Latvian and Estonian victory, the collapse of Niedra’s government, and the restoration of Kārlis Ulmanis’s Provisional Government.

The Battles of Cēsis were one of the crucial turning points in the Latvian War of Independence: they determined whether Northern Vidzeme would be secured by forces loyal to Ulmanis’s Provisional Government or by Niedra’s government aligned with German political interests. The victory at Cēsis became an important symbol of Latvian and Estonian military cooperation.
