of the 27th, 28th, 29th and 53rd Infantry Divisions, the headquarters and administration of the XX Army Corps laid down their arms. 12 generals, 67,500 officers and soldiers, 295 guns and 170 machine guns were captured. During February 23-24, the remnants of the regiments that managed to seep through the German positions came to Grodno: a detachment of Major General E.

However, it was in this operation on the Russian side that the command, both at the level of the front and the army, and at the level of the corps, showed the worst qualities - lack of confidence in victory, contradictions and errors in assessing the situation, and stiffness in the initiative. These flaws cost the Russian soldiers dearly. Although there was no radical turning point in the course of the war as a result of the operation (such a task was not set), the German troops managed to finally defend East Prussia, completely liberate it from Russian troops and minimize, as it turned out later, the possibility of a new invasion of Germany. Russian troops captured 40 officers and 1,666 soldiers, captured 15 machine guns and 6 guns. However, the damage of the Russian troops was disproportionately greater. If on the German side from the commanding staff one general (brigade commander), one lieutenant
