Read a WW2 account from german soldiers about russians. They started feeling pretty sorry for themselves because the russians seemed to have unending supply of artillery , tanks and troops. Everyone seems to agree battle for stalingrad in late 1942 was turning point of war and yet, it wasn’t until may 1945 that they planted their flag over berlin. War can be a slow grinding process. The germans in WW1 never captured verdun but forced french to bleed their forces white defending it. I think it’s a pretty good parallel to bahkmut battle.
