There was also a group of troops in the Donbas who, because of Mariupol, have also surrendered.
The UK Column News May 18th had a good section on this surrender, beginning around 23:20: ‘Surrender’/’Evacuate’ at Azovstal Mariupol while Russia advances. Inspite of Russian troops professionalism and ‘humane’ treatment of the prisoners, the msm continue to vilify them/Putin.
