British campaign in the Baltic (1918–1919)
1918–1919 British naval intervention during Russian Civil War

The British campaign in the Baltic 1918–1919 was a part of the Allied intervention in the Russian Civil War. The codename of the Royal Navy campaign was Operation Red Trek. The intervention played a key role in enabling the establishment of the independent states of Estonia and Latvia. It failed to secure the control of Petrograd by White Russian forces, which was one of the main goals of the campaign.
Context
Launched in the wake of the Armistice of 11 November 1918 which ended World War I and the German military occupation of the Baltic countries, the purposes of Operation Red Trek were to stop the rise of Bolshevism in the area, to support the newly independent countries of Estonia and Latvia, to protect British interests, and to extend the freedom of the seas.
The situation in the Baltic countries of Latvia and Estonia in the aftermath of World War I was chaotic. The Russian Empire had collapsed and Bolshevik Red Army, pro-independence and pro-German forces were fighting across the region. Riga had been occupied by the German army in 1917 and German Freikorps and Baltic-German Baltische Landeswehr units were still active in the area. Estonia had established a national army and, with the support of Finnish volunteers, was defending against an attack by the 7th Army of the Soviet Russian Red Army.

Why this record matters
The phrase “1918–1919 British naval intervention during Russian Civil War” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q4147516. Authority coordinates are 58.617, 20.417. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1918, 1919 and 1917.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
