The Crimea Peninsula was ablaze with conflict between the United Kingdom, France, and Russia, more precisely, an offensive by the British and French while Russia was desperately defending.
Their disadvantage in weaponry and equipment was a critical issue, unlike the Russian Army in the Balkan Peninsula, which had completely upgraded to Austrian equipment, achieving parity with the British and French.
The Russian forces on the Crimea Peninsula, however, were not so lucky. Originally consisting of second-line troops and hurriedly thrown into battle, coupled with the bureaucratic corruption within the Tsarist Government, multiple factors contributed to their tragedy.
By this time, Nicholas I had already decided to fully upgrade to Austrian military equipment. However, due to the domestic introduction of production lines, bureaucrats who were out of touch gave the orders to local military enterprises.
