In the wake of the February Revolution of 1917, Radkevich remained in the Russian Army of the Russian Republic under the Russian Provisional Government.
On 25 April 1917 be became the assistant to the commander of the Petrograd Military District, Lavr Kornilov, and on 29 April 1917 he relieved Kornilov as commander of the district.
On 6 May 1917 he again became a member of the Military Council.

In the October Revolution in 1917, the Bolsheviks toppled the Russian Provisional Government and the Russian Civil War began.
On 21 March 1918, Radkevich was dismissed from the service, and he officially retired again in November 1918.

In 1918 he was mobilized in the Red Army.
In the early 1920s he taught topography at the Odessa Artillery School.
G. D. Plaskov , then a cadet, recalled in 1969 in Under the Roar of the Cannonade:
A 72-year-old Radkevich, a former tsarist general, left a fond memories.
A cheerful, humorous old man, he often often came [to class] by bicycle with a bag full of groceries.
He was well provided for financially; on the orders of the Revolutionary Military Council of the Republic [i.e., the Russian Soviet Federated Socialist Republic], he received a special ration.
Before starting classes, Radkevich opened his bag and laid out tiny sandwiches on a snow-white napkin. "
Sir Junker, do not offend the old mother" — so he called his wife — "she prepared it for you, eat, we still have left, do not be shy!"
It was impossible to refuse: the eyes of this wise and kind man shone very kindly.

He cared for us as sons.
In the evenings he came to our room [and] sat down at the table.
He wiped his sweating face and said in a voice that allowed no objections: "Come on, gentlemen, show your calendars.
How did you prepare for tomorrow?" [
We would] carefully check our notes [and] drawings, correct errors, explain them.
Somehow he brought a beautiful folder, pulled out from it photographs of his sons, officers, just like him, who had switched over to serve the people.
He joyfully, excitedly talked about his meeting with Lenin.

I agreed with him about everything, we understood each other perfectly.
And I immediately obeyed him, and the three of us joined the Red Army.
The "old mother" was against it, but we persuaded her ...
He talked a lot about the Russo-Japanese [War] and World War I. "And you know, in 1915, I presented to His Majesty the Emperor of Russia documents on the subject of the assignment of the rank of Colonel Nikolai Iosifovich Bettikher; in those years he commanded a heavy artillery division for me..." And it became clear to us why the commandant of the school was pulled at the sight of this teacher.

Radkevich was always busy.
The cleanly decorated topography room was filled by cadets during free hours.
Maps, schemes of various scales hung on the walls, [and] educational exhibits were neatly arranged.
On the tables lay massive multi-colored pencils, erasers, workbeds, sheets of Whatman paper, tracing paper — the general brought most of these scarce things from home.
Radkevich circulated among the cadets, advised them, showed them things.
We studied here not only topography - the old teacher willingly gave advice on other disciplines.


When choosing a presidium at ceremonial meetings, he received dozens of votes.
Shy, he climbed onto the stage and sat modestly in the second row. "
The commissioner or the head of the school approached him and sat next to him."

In 1923, Radkevich retired due to age.
He died in 1930.
