Rovno
a small city in Volhynia, Russia, but more important as a fort.
It formed one of a triangle of forts, the other two being located at Lutsk and Dubno. Rovno was first fortified in 1887, and consisted of a system of seven forts in the form of a semi-circle, at a distance of from four to six miles from the city itself, and with a circumference of about twenty miles. During the early part of the World War Rovno served as the base of a Russian invasion of Austria-Hungary, until after the retreat of the Russian army, when it fell into the hands of the Germans. After the final defeat of Germany the forts again fell into the hands of the Russians.
During the war between Soviet Russia and Poland, in the spring of 1920, the Poles attacked Rovno, and were reported to have taken it, but at the end of the campaign it was still in the hands of the Bolsheviki.
