Vladimir Putin's war effort has been left in ruins after his top commander - Valeriy Gerasimov - was reportedly wounded and forced to flee the country after a Ukrainian ambush attack. The devastating attack is a huge blow to the Kremlin after President Putin had personally sent General Gerasimov to rescue the stalled war ahead of the May 9 Victory Day parade. General Gerasimov, who is the chief of staff of the Russian army, had been sent to the region to take personal control of the all-out assault on the Donbas region.
