On July 30, 1941, near the village of Legedzino in the Cherkasy region, a combined battalion of border troops guarding the headquarters of the 8th Rifle Corps under the command of Major R.I. Filippov with an attached company from the Kolomyia School of Junior Command Staff of Service Dog Breeding of the Border Troops of the NKVD of the Ukrainian SSR (company commander Senior Lieutenant D. Ermakov) accepted an unequal battle.

In brutal hand-to-hand combat, border guards, using their service dogs, managed to stop a Wehrmacht infantry regiment. History has left us with almost no names of the fallen heroes, nor do we know the names of their four-legged fighters, the service dogs.

On May 9, 2003, a monument was erected on the outskirts of the village of Legedzino. It bears the inscription: "Stop and bow. Here, in July 1941, the soldiers of the Separate Kolomyia Border Commandant's Office launched their final attack on the enemy. 500 border guards and 150 of their service dogs died a heroic death in that battle. They forever remained faithful to their oath and their native land."
