The Second Prussian ArmyAt 14:30 Crown Prince Frederick finally arrived with the main bulk of his almost 100,000 men, having marched with all possible haste all morning, and hit the Austrian right flank retiring from Swiep Forest while the Prussian artillery pounded the Austrian centre. By 16:00 the last individual counter-attacks by the Austrian I and VI Corps were broken, even as Benedek ordered a withdrawal. Lt. General Friedrich Hiller von Gärtringen’s 1st Prussian Guard reached the Austrian artillery, forcing them to stop reforming an artillery line and pull back. He had attacked because he saw the artillery as holding together the Austrian position, and his attack destroyed the lone cavalry battery that stayed to fight, and forced the others to flee, along with their reserves.At this point, having taken severe casualties, lacking artillery and cavalry cover, the high ground in enemy hands and the centre being rolled up, the position for the Austrians deteriorated rapidly. The Second Prussian Army completely broke through the Austrian lines and took Chlum behind the centre. The Army of the Elbe, which had merely held position after the early morning bloodying by the Austrian artillery and the Saxon infantry, attacked and broke through the Austrian left flank. It seized Probluz, and proceeded to destroy the Austrian flank. The Prussian king ordered all remaining forces into the attack all along the line, which had been slowed by the final counter-attack from the battalions of Brigadier General Ferdinand Rosenzweig von Dreuwehr’s Austrian brigade. The arriving reinforcements joined the fight just as the Austrians had forced the 1st Prussian Guard back to Chlum. The result was a decisive shock of firepower which collapsed the Austrian line. The Prussian advance was so rapid that Benedek ordered a series of cavalry counter charges to
back up his artillery and cover the general retreat he ordered at 15:00. These were successful at covering the Austrian rear, keeping the bridges over the Elbe open for retreating Austrian soldiers, and preventing pursuit by the Prussians, but at a terrible cost: 2,000 men and almost as many horses were killed, wounded or captured in the action. Benedek himself crossed the Elbe near 18:00 and several hours later informed the emperor that the catastrophe of which he had warned had indeed occurred.High CasualtiesThe battle ended with a high casualty rate for both sides. The Prussians had nearly 9,000 men killed, wounded or missing. The Austrians and allies had over 44,000 men killed, wounded or missing, with 22,000 of these being prisoners. What made the losses for the Austrians higher was that Austria had refused to sign the First Geneva Convention. Hence their medical personnel were regarded as combatants, and withdrew from the field with the main bulk of the forces, leaving the wounded to die on the field.Aftermath Königgrätz was the decisive battle of the Austro-Prussian War; an armistice signed at Prague ensued three weeks later. It provided a great opportunity for Prussian statesmen, by clearing a path toward German Unification, in particular with the Little Germany or Germany without Austria solution, with the subsequent foundation of the North German Confederation.The French public resented the Prussian victory and demanded “Revanche pour Sadova” or “Revenge for Sadowa”, which formed part of the build-up to the Franco-Prussian War of 1870.Reproduced from Wikipedia
