On September 6, 1917, the Riga operation of the German army concluded, resulting in the Germans capturing Riga.

Before 1914, Riga was one of the five largest cities in the Russian Empire, serving as an important industrial center and port. Its loss was a significant success for Germany and dealt a serious psychological blow to the Russian army. The ease with which this victory was achieved symbolized the decline of Russian military power.

General Denikin wrote about this:

"We lost the wealthy industrial city of Riga along with military equipment and supplies. But most importantly, we lost a reliable defensive line, the fall of which constantly threatened both the position of the Dvina front and the direction towards Petrograd."

These events prompted General Kornilov to once again demand that the Provisional Government take measures to restore order in the country and the army. A few days later, a conflict would erupt between Kornilov and Kerensky, known as the 'Kornilov Mutiny.'
