  On June 22, 1941, the 1st Mech Corps was stationed in the Leningrad district at Pskov.  The
  corps suffered relatively light casualties in the opening onslaught.  On July 4 however, the corps was
  ordered to attack the 1st Panzer Division crossing the river at Ostrov.  During the fighting, the 6th Panzer
  Division counterattacked the 1st Mech Corps and pushed it back out of Ostrov with heavy casualties.
  The 1st Mech Corps was officially disbanded on July 15, with the surviving elements mostly being
  attached to other units.
