Why did Hitler shift troops away from the drive toward Moscow in 1941?

In 1941, Adolf Hitler shifted troops away from the drive toward Moscow primarily due to strategic disagreements with the Oberkommando des Heeres (OKH) regarding the objectives of Operation Barbarossa.12

While the OKH advocated for Moscow as the primary target, Hitler insisted that the main effort be directed southeastward through Ukraine and the Donets Basin toward the Caucasus, while simultaneously ordering a secondary push toward Leningrad. This diversion of forces facilitated a massive pincer movement around Kyiv, which resulted in the capture of 520,000 Soviet troops by late September.12

These arguments and the subsequent redeployments consumed much of August, causing a significant delay in the overall offensive. By the time the German forces resumed their advance on Moscow in October, they faced deteriorating weather conditions, logistical challenges, and the emergence of fresh Soviet reserves, which ultimately contributed to the failure of the campaign to capture the capital before the onset of winter.123
