Why did Hitler divert German forces from the drive toward Moscow in August 1941?

In August 1941, Adolf Hitler diverted German forces away from the direct drive toward Moscow due to a fundamental disagreement with the German Army High Command (OKH) regarding strategic objectives. While the OKH advocated for Moscow as the primary target, Hitler insisted on shifting the focus southeastward through Ukraine and the Donets Basin toward the Caucasus, alongside a secondary effort against Leningrad.12

This decision was heavily influenced by the success of Field Marshal Gerd von Rundstedt’s forces in southern Ukraine, which encouraged Hitler to pursue a massive pincer movement to encircle Soviet troops near Kiev. By ordering Gen. Paul Ludwig von Kleist to wheel northward and Gen. Heinz Guderian to move southward, Hitler achieved a significant tactical victory, capturing over 500,000 prisoners by late September. However, this strategic diversion cost the German army the most favorable summer months for campaigning, ultimately delaying the final push on Moscow until October, when weather conditions had already begun to deteriorate.12
