Russians routed

DR YURI FELSHTINSKY (Letters), listing Russian mobilisations, omitted to mention the one in 1919-20 when the Red Army battled against Poland. The eventual result of the Russo-Polish war was a rout of the Russians; the Treaty of Riga in 1921 ceded territory to Poland. This is the example Ukraine should bear in mind as it fights for its territory.
