Light Brigade was looked upon as a glorious but wasted sacrifice of good men and horses, recent historians believe that the charge of the Light Brigade succeeded in at least some of its objectives. The aim of any cavalry charge is to scatter the enemy's lines and frighten the enemy off the battlefield. The Charge of the Light Brigade so unnerved the Russian cavalry, which had been routed by the Charge of the Heavy Brigade, that the Russians were set to full-scale flight. The shortage of men led to the failure of the British and the French to follow up on the Battle of Balaclava, which led directly to the much bloodier Battle of Inkerman. On 5 November 1854, the Russians attempted to raise the siege at Sevastopol with an attack against the allies, which resulted in another allied victory. Winter of 1854–1855 Winter weather and a deteriorating supply of troops and materiel on both sides led to a halt in ground operations. Sevastopol remained invested by the allies, whose armies were hemmed in by the Russian Army in the interior. On 14 November, the "Balaklava Storm," a major weather event, sank 30 allied transport ships, including , which was carrying a cargo of winter clothing. The storm and the heavy traffic caused the road from the coast to the troops to disintegrate into a quagmire, which required engineers to devote most of their time to its repair, including by quarrying stone. A tramway was ordered and arrived in January with a civilian engineering crew, but it took until March before it had become sufficiently advanced to be of any appreciable value. An electrical telegraph was also ordered, but the frozen ground delayed its installation until March, when communications from the base port of Balaklava to the British HQ was established. The pipe-and-cable-laying plough failed because of the hard frozen soil, but nevertheless of cable were laid. The troops suffered greatly from cold and sickness, and the shortage of fuel led them to start dismantling their defensive gabions and fascines. In February 1855, the Russians attacked the allied base at Eupatoria, where an Ottoman army had built up and was threatening Russian supply routes. The Russians were defeated at the Battle of Eupatoria, leading to a change in their command. The strain of directing the war had taken its toll on the health of Tsar Nicholas. Full of remorse for
