<P> Meanwhile, to support his weak right flank, Napoleon ordered Davout's III Corps to force march all the way from Vienna and join General Legrand's men, who held the extreme southern flank that would bear the heaviest part of the Allied attack . Davout's soldiers had 48 hours to march 110 km (68 mi). Their arrival was crucial in determining the success of the French plan . Indeed, the arrangement of Napoleon on the right flank was very risky as the French had only minimal troops garrisoning there . However, Napoleon was able to use such a risky plan because Davout--the commander of III Corps--was one of Napoleon's best marshals, because the right flank's position was protected by a complicated system of streams and lakes, and because the French had already settled upon a secondary line of retreat through Brunn . The Imperial Guard and Bernadotte's I Corps were held in reserve while the V Corps under Lannes guarded the northern sector of the battlefield, where the new communication line was located . </P> <P> By 1 December 1805, the French troops had been shifted in accordance with the Allied movement southward, as Napoleon expected . </P> <P> The battle began at about 8 a.m. with the first allied lines attacking the village of Telnitz, which was defended by the 3rd Line Regiment . This sector of the battlefield witnessed heavy fighting in this early action as several ferocious Allied charges evicted the French from the town and forced them onto the other side of the Goldbach . The first men of Davout's corps arrived at this time and threw the Allies out of Telnitz before they too were attacked by hussars and re-abandoned the town . Additional Allied attacks out of Telnitz were checked by French artillery . </P> <P> Allied columns started pouring against the French right, but not at the desired speed, so the French were mostly successful in curbing the attacks . Actually, the Allied deployments were mistaken and poorly timed: cavalry detachments under Liechtenstein on the Allied left flank had to be placed in the right flank and in the process they ran into and slowed down part of the second column of infantry that was advancing towards the French right . At the time, the planners thought this slowing was disastrous, but later on it helped the Allies . Meanwhile, the leading elements of the second column were attacking the village of Sokolnitz, which was defended by the 26th Light Regiment and the Tirailleurs, French skirmishers . Initial Allied assaults proved unsuccessful and General Langeron ordered the bombardment of the village . This deadly barrage forced the French out, and at about the same time, the third column attacked the castle of Sokolnitz . The French, however, counterattacked and regained the village, only to be thrown out again . Conflict in this area ended temporarily when Friant's division (part of III Corps) retook the village . Sokolnitz was perhaps the most fought over area in the battlefield and would change hands several times as the day progressed . </P>
