They have passed, leaving destruction and death.
And they retreated by planting mines everywhere to trigger another long trail of blood among Ukrainians trying to get back to normal in the liberated areas.
Before leaving, the Russians hid bombs everywhere, even in the washing machines of the houses abandoned in a hurry and in a fury.
They left deadly traps in all "places where they spent the night", denounces the Interior Ministry of Kiev, telling of mines placed on the entrance doors, under cars, between sofas and beds.
By launching the maximum alert: the threat is very high, citizens must not return until the difficult job of the bomb squad is completed.
That of mines is an alarm that has been ricocheting for days in areas of Ukraine from which Russian forces have withdrawn.
President Vlodymyr Zalensky himself had also launched it, denouncing another atrocity in atrocities: the corpses transformed into lethal weapons with devices ready to explode in the last act of mercy on those who move them to give them burial.
While the photos of mines in washing machines, in shopping bags, among the furniture of abandoned houses to escape from bombs go around the world, it was a video released by the president that showed the deadly traps.
Green or other colors, light and wavy shapes, harmless air, ten centimeters in all, two wings with a small cylinder in the center that whirl when thrown high and spread over the territory: they are the 'butterfly' anti-personnel mines that the Russians use in quantity and they explode when picked up and handled.
The danger, the Ukrainian military warns, also comes from unexploded and camouflaged devices that "can look like a toy, a mobile phone, a ballpoint pen: any object can be filled with explosives".
In the Kharkiv area, Human Rights Watch accused days ago, Russia used banned anti-personnel mines.
They are the POM-3, also known as 'Medallion', equipped with a sensor to detect an approaching person and emit an explosive charge.
The subsequent detonation of the charge and the metal fragments it projects can cause death and injury within a radius of 16 meters.
