White Army offensive On September 28, 1919, the White Northwestern Army launched the offensive. Within the week,
Luga had been taken, railroads from Pskov to
Petrograd had been cut off, and
Iamburg had been taken by October 11. On October 20, some units had made it to
Pulkovo Heights, within the suburbs of Petrograd. The 3rd Infantry Division of the Army had ignored orders to cut the Moscow-Petrograd railway at
Tosno to reach Petrograd first.
Red Army counteroffensive Trotsky had traveled north to the city in an effort to rally a defense. The railway junction at Tosno, which was left alone, had allowed supplies to be sent to the defenders of Petrograd from Moscow. On October 21, the Red Army attacked, pushing the Whites back from
Pulkovo, and retook
Tsarskoe Selo and
Pavlovsk two days later. Soon, the 7th Army attacked east while the 15th Army attacked south, taking back Luga on the 31st. On the second anniversary of the
October Revolution, the two armies linked up east and south of
Iamburg. ==Aftermath==
