As the Russo-Japanese War broke out in early 1904, Nemirovich-Danchenko travelled to Manchuria as a "Novoye Slovo" war correspondent. He arrived at Port Arthur together with a shipment of ammunition just before the start of the Siege of Port Arthur. Staying in the fortress, in the first year of his mission there he published 350 reports which had "an astounding success". Nemirovich-Danchenko served again as a correspondent in World War I. His popularity with readers never waned; not long before his emigration in 1921 a "Vestnik Literatury" reviewer described him as "one of our best stylists" and a "master of poetry in prose" whose "books are invariably among the most in demand in libraries ".
