Major Battles in the Crimean War

The Battle of Balaclava was fought on 25 October 1854 and was part of the Anglo-French-Turkish campaign to capture the port and fortress of Sevastopol, which was the Russian main naval base on the Black Sea. The battle followed the earlier Allied victory in September at the Battle of the Alma. The Crimean War, known for the 'Charge of the Light Brigade', would hugely shift the balance of power in Europe and in a way make way for WW1.
The highest ranking officers and the ones to blame are Lord Raglan, Lord Cardigan , Lord Lucan and Lord Nolan . However, the most influential officer responsible was Lord Raglan as he was in command at the time.
Lord Raglan was overall commander of the British forces and had intended to send the Light Brigade to pursue a retreating Russian artillery battery. Due to terrible communication and confusing orders the Light Brigade was instead sent on an assault against a different battery which was more prepared and had a huge strategic advantage.
The Light Brigade reached the battery under direct fire and scattered some of the gunners, the brigade was forced to retreat. The assault ended with very high British deaths and gain to the Army. 

The Battle of the Alma, 20 September 1854, which is usually considered the first battle of the Crimean War, took place just south of the River Alma. An Anglo-French force commanded by General St. Arnaud and Lord Raglan defeated the Russian army, which lost around 6,000 troops.

General St. Arnaud  was a French solider and he served as French Minister of War until the Crimean War when he then became Commander-in-chief of the army in the East. He commanded in the Crimean War with Raglan, both commanders led the allies to the first victory which set morals high for the British, conditions slipped more and more throughout the war due to leadership not being up to a good standard and the supplies the Army needed were not there due to the government being run by under qualified aristocrats. This impacted the war because if they hadn't won this battle, they would have found themselves becoming more prepared for events throughout the war which as I know would have saved the Army countless deaths and losses at the hands of the Russian army.
