The siege of Novogeorgievsk was a battle of World War I fought after the Germans broke the Russian defenses in Paul von Hindenburg's Bug-Narew Offensive.

For the most part, the infantry was represented by the Landwehr, Landsturm and reserve regiments; on the Russian side, the militia made up half of the garrison, but, unlike the Germans, they had no combat experience.

[11] Spy mania, caused by anti-Semitic sentiments among the military environment of the Warsaw fortified region, worsened significantly with the outbreak of the First World War.

Since the beginning of the First World War, the persecution of spies in the fortress acquired increasingly grotesque and, as a rule, anti-Semitic in spirit forms, and sometimes the reason for this was the unjustified actions of the command itself.

Later, in May 1915, apparently not satisfied with the results of the local implementation of such a policy, Russian Headquarters issued an order to practice taking Jews hostage along the entire front.

[13] Particularly serious damage to the morale of the garrison was caused by the death of the chief of engineers of the fortress, Colonel Korotkevich-Nochevny, who was killed during an inspection of forward positions.

Gossip transformed this tragic incident into a voluntary transition with a lot of vital documentation to the enemy’s side of the chief of defense of the southern department of the fortress, Major General A. Krenke, who did not participate in the trip at all.

[14] However, these rumors had a reliable basis, since the Germans captured Korotkevich’s portfolio, the general plan for the fortifications of Novogeorgievsk, indicating the locations of heavy batteries.

[15] Thus, both the officials from the front command headquarters and the officers of the Novogeorgievsk garrison itself, through ill-considered actions, only raised the level of anti-Semitism in the military environment, in the region most densely populated by Jews.

[16] Novogeorgievsk was surrounded on 10 August and the bombardment began few days later and was concentrated on the north-eastern portion of the defenses, lying north of the Vistula River.

Major General P. Venevitinov, commander of the Pomekhovsky sector, ordered to clear the forts and retreat to the second line of defense, blowing up the fortifications.

At Fort II and III, the Russian 249th Infantry Regiment counterattacked Pfeil's Landwehr Brigade; in the midst of the battle, the German field artillery fired all the ammunition and could be captured, but the heavy batteries advanced forward helped repel the onslaught.

[20] According to the Russian military researcher Alexander Plekhanov: “In July 1915, the advanced units of General Hans von Beseler reached Novogeorgievsk.

The Germans who occupied the fortress were surprised to find that almost all the guns remained intact, in addition, they received huge reserves of shells, food and ammunition.
