This offensive covered the operations of 2nd Belorussian Front from 6–14 August, after their completion of the Belostock Offensive, with the objective of the fortified area at Osowiec on one of the tributaries of the Narew River.
The defense of Osowiec is comparable to the 1916 battle of Verdun, in France.
Osowiec fortified region - 60 km, 8 centers of resistance, 35/59/594 (in Poland)
Osovets is the Russianised version of the Polish name Osowiec / Ossowiec / Ossowitz.
The Border Defence Corps Regiment "Sarny", which operated the Area, was very well trained, and its soldiers, including Władysław Raginis, distinguished themselves during the Battle of Wizna (see Polish September Campaign), and in other battlefields in the area of Osowiec and Upper Silesia, where up to 80% of KOP died or were wounded.
