Russian Bolsheviks of Yakov Tryapitsyn launched a surprise attack on an American army camp at Romanovka, near Vladivostok.

Romanovka and the Suchan Valley Campaign that followed were the final major engagements of the Russian Civil War involving the United States.

The Bolsheviks, numbering around 400 men, then attempted to surround the American position but the latter retreated, first to a large wood pile and then again to the back of a cabin, all while under heavy fire.

The messenger was shot while doing this but he managed to flag down a passing supply train guarded by a platoon of American troops under Lieutenant James Lorimar.

On the same day, men of the 27th Infantry engaged partisan forces at Kraefski and Shmakovka, resulting in the wounding of six more American soldiers and another Bolshevik retreat.
