FPI Timeline: Russian Aggression in Ukraine since the September 2014 Cease-Fire

February 10, 2015

This week, the leaders of Russia, Ukraine, France and Germany will meet in Minsk to pursue a de-escalation of the war between Ukraine’s democratic government and the Russian-backed separatists that control key portions of the country’s eastern provinces. Employing heavy weapons and technology provided by the Kremlin, the separatists have continually violated the September 2014 cease-fire known as the Minsk Protocol. Since the cease-fire was signed, Russian-backed separatists have seized 500 square miles of Ukraine’s territory, including the Donetsk airport.

The invasion of Ukraine is only one facet of a Russian campaign to intimidate its neighbors and sow division within NATO. In recent months, Russia has kidnapped an Estonian intelligence officer on Estonian soil, warned Latvia of “unfortunate consequences” for its alleged mistreatment of ethnic Russians, forced Sweden to re-route a civilian airliner to prevent a collision with a Russian military jet, flown strategic bombers over the English Channel, and sent unannounced formations of military aircraft into European air space.

The timeline below traces the evolution of Putin’s campaign to subvert Ukrainian sovereignty. The Foreign Policy Initiative (FPI) believes it will be of use to lawmakers and their staff as they seek to formulate a more effective American response to the ongoing aggression. For an overview of events in Ukraine leading up to the Minsk Protocol, please see FPI’s Fact Sheet: Timeline of Russian Aggression in Ukraine and the Western Response.


September 5, 2014: The Ukrainian government agrees to a cease-fire, known as the Minsk Protocol, after the success of an offensive by Russian-backed separatists. The Russian government was the principal architect of the agreement, to which Kyiv and the separatists consented.

September 20, 2014: Ukrainian forces and pro-Russian separatists revise their two-week-old cease-fire, defining a minimum distance of nine miles from the front lines as a buffer zone free from artillery and heavy weapons.

October 16, 2014: Russian President Vladimir Putin issues a warning: “We are hoping that our partners will understand the imprudence of attempts to blackmail Russia, [and] remember what discord between large nuclear powers can do to strategic stability.”

November 11, 2014: As fighting in Ukraine escalates, General Breedlove tells reporters: “The cease-fire is in name only at this point.  The violence increases day by day.” Pentagon officials claim that Russia has amassed approximately 8,000 troops on the Ukraine border.

January 15, 2015: In the midst of a months-long stalemate at the Donetsk airport, separatists intensify their efforts to oust Ukrainian forces. According to Reuters, “the complex, a battered wreck with its runways cratered by shell explosions, has not functioned as an airport since hostilities erupted last April but it remains an important symbol for both sides.”
