Hello to all
Independent Operational Group "Narew".
Therefore, the HQ of the SGO "Narew" decided:
1. Concentrate the main defense effort on the Łomża-Nowogród-Ostrołęka section.
2. Close the directions leading the enemy to Białystok in the Osowiec area and in the Wizna area.
3. The cavalry brigade was to cover the Grodno direction and the northern wing of the group.
The Narew, Biebrza and Netta front was divided into five defensive sections: Ostrołęka, Nowogród-Łomża, Wizna, Osowieć and Augustów.
By decision of the Commander-in-Chief, on August 29, Group "Grodno" was formed with the task of defending the Augustów Forest and the area west and north of Grodno. The above decision led to a significant reduction of the defense section of the SGO "Narew".
SGO "Narew" initially consisted of the following units: 18th Infantry Division, 33rd Reserve Infantry Division, Suwalska and Podlaska BK (Cavalry Brigades). The Group was then strengthened with the allocation of non-divisional units: KOP Regiment (*) with one battery, one heavy machine gun battalion (not attached), one light artillery squad (not attached), three National Defense battalions (only one was organized), in the "Augustów" Regiment. Aviation assigned to the group consisted of the 13th Escort Aviation Squadron, the 51st Escort Aviation Squadron, the 51st Reconnaissance Squadron, the 151st Fighter Squadron and the 9th Liaison Platoon. The Group's aviation Commander was Lieutenant Colonel Nazarkiewicz.
The three western sections were to be defended by the 18th Infantry Division, Osowiec received a separate crew (from the composition of the 33rd Infantry Division), BK Suwalska was to operate in the Augustów section, reinforced with KOP infantry. The troops had to defend the lines of the Narew and the Biebrza closing the main crossings of these rivers. In case of strong pressure, a planned withdrawal towards the designated lines was foreseen, where, as regards the western sections, the intervention of the reserve forces, composed of the 33rd Infantry Division (without the 135th Infantry Regiment with the 2. Group of the 32nd Light Artillery Regiment (pal), which constituted Osowiec's crew) and the BK Podlaska after their return from the front. They were to concentrate in the Czerwony Bór (Cavalry Brigade) area and in the area southwest of Łomża.
For the period of initial operations, BK Podlaska received a special task: "Group in the Stawiski-Korzeniste area to cover the concentration of the group's troops in the area south of Łomża. Prepare to leave the Stawiski-Korzeniste area for a deeper reconnaissance on Bialla-Johannisburg (Biała -Jańsbork). In case of withdrawing from the first line, go to the group reserve".
At the end of April 1939, the construction of fortifications and modernization of the old Russian fortress in Osowiec began in the section designated for SGO "Narew". Firstly, fortifications were erected in the area of Wizna and Giełczyn, then in the area of Łomża, Osowiec, Nowogród and the Augustów forest. It was decided to base the Łomża fortifications on outdated forts, supplementing them with light dugouts. Light shelters were built near Ostrołęka, as well as in the Augustów area.
