The detachment marched from Iași on the Romanian front to the Don, to join the White Russian Volunteer Army of General Lavr Kornilov and fight the Bolshevik enemy together.
Colonel Drozdovsky, a staunch monarchist, had gathered around him in Iași after the October Revolution a detachment of between 800 and 1500 men, most of whom were young officers.
Under pressure, the Romanians even gave trains to transport the troublesome army to Kishinev in order to get rid of them as soon as possible.
Leaving Rostov, Drozdovsky's men helped the Don Cossacks, in rebellion against Bolshevik power, to retake Novocherkassk.
On the evening of May 7, 1918, the "Drozdovsky" detachment arrived in Novocherkassk under the acclamation of the inhabitants, bringing an end to the "Romanian march".
