Definition of "dacha"

The belt is full of dachi, i.e., summer villas, all now closed. […] Most of the dachi are small; but some large, sumptuous, and more securely fenced, a few with iron palisades to insure privacy. […] There are no roads in the environs of Odessa, except among the dachi by the shore.

Stalin’s was several thousand strong, and the NKVD in addition kept other units at a state of readiness. The road to his country dacha, some twenty miles away, was guarded by over 3,000 agents, with cars, telephone connections, etc. When Stalin was actually en route, the road was virtually under martial law.

The Ambassador warned him of the consequences if his mission to Moscow were a failure, both to Churchill's position at home and to Russia's prospects in the war. He insisted that he should not allow himself to be offended 'by a peasant who didn't know any better'. Churchill listened in silence, then returned to the dacha leaving Clark Kerr outside.
