“The biggest tank battle of all time was at Kursk not Kharkov.”
You’re right, I stand corrected.
At Kursk battle there were more than 4,000 tanks involved.
The Battle of Kursk involved countless tanks but it was very much like a World War I battle in that relatively few kilometers were gained at a huge cost due to the overall equality of the forces involved. The Germans were faced with the question of continuing the offense at a risk of “reinforcing failure”. Should they break off the offensive... or ...make more pushes that could lead to success.
Field Marshall von Manstein was skeptical of overall success but favored continuing the meat grinder as it trapped the Russians to committing their forces at this predictable place rather than giving them the initiative to develop attacks at strategic spots of their choosing.
