The source for the following details about the Garabandal apparition and Russia role in future events  come from German author Albrecht Weber’s book: Garabandal—The Finger of God and the website 1260.org

“In an interview Miss Christine Bocabeille  spoke with  Garabandal visionary Mari Loli about  the coming  “Warning”. She asked the visionary: “If you are not allowed to tell me the exact year of the Warning, perhaps you could tell me approximately when it will happen.”

Mari Loli:  “Yes, it will be at that time when the world will most need it.”

Christine: “When will that be?”

“When Russia will unexpectedly and suddenly overrun and overwhelm a great part of the free world. 

God does not want this to happen so quickly. In any case the Warning will come when you will see that Holy Mass cannot be celebrated freely anymore; then it will be that the world will most need the intervention of God.

The most famous of the Garabandal Visionaries also spoke of Russia as the linchpin to the Warning and the “Great Miracle: 

Conchita said:  “The pope will go to Russia, to Moscow. As soon as he returns to the Vatican, hostilities will break out in different parts of Europe.” We don’t know when all this will happen,

Conchita mentioned that Padre Pio, during her visit with him, said to her “The great wonder of God’s Miracle must be paid for with much blood throughout Europe.“  Since this information is new to many English readers we want to again say Mr. Weber is the source. 

The website  1260.org sums up what happens after Russia hostilities against the world begin:

 A worldwide takeover led by Russia will appear to have succeeded and in the midst of this frightful aggression will be a harrowing persecution of the Church. 

Priests will have to go into hiding, the churches boarded up and it will become very difficult for the faithful to practice their religion. It will seem as though the Church had disappeared. The duration of this persecution is not known but it will take an act of God, the Warning, to stop it. To close on a positive note, we again quote from Fr. Brennan’s 1983 article:

“As a result of all this there will be a turning to God that will match the apostasy from God that preceded it, with the result, as Our Lady said at Fatima, that “an era of peace will be granted to humanity.“

This will be a peace such as the world has never known.
