After the day was won, Lord Raglan pressed Saint-Arnaud to the pursuit of the enemy; but the French general was weakened by illness, and his energies failed. Had Lord Raglan's counsels been followed, the future disasters of the allied armies might have been averted. The battle was fought on the 20th of September; but the allied armies halted on the Alma until the 23d, instead of pushing on directly to Sebastopol, twenty-five miles to the south. This long halt was owing to Saint-Arnaud, who felt it was necessary to embark the wounded on the ships before encountering new dangers. This refusal of the French commander to advance directly to the attack of the forts on the north of Sebastopol was unfortunate, for there would have been but slight resistance, the main body of the Russians having withdrawn to the south of the city. All this necessitated a flank movement of the allies, which was long and tedious, eastward, across the north side of Sebastopol to the south of it, where the Russians were intrenched. They crossed the Belbec (a small river) without serious obstruction, and arrived in sight of Sebastopol, which they were not to enter that autumn as they had confidently expected. The Russian to whom the stubborn defence of Sebastopol was indebted more than to any other man,--Lieut.-Colonel Todleben,--had thoroughly and rapidly fortified the city on the north after the battle of the Alma. It was the opinion of Todleben himself, afterward expressed,--which was that of Lord Raglan, and also of Sir Edmund Lyons, commanding the fleet,--that the Star Fort which defended Sebastopol on the north, however strong, was indefensible before the forces that the allies could have brought to bear against it. Had the Star Fort been taken, the whole harbor of Sebastopol would have been open to the fire of the allies, and the city--needed for refuge as well as for glory--would have fallen into their hands. The condition of the allied armies was now critical, since they had no accurate knowledge of the country over which they were to march on the east of Sebastopol, nor of the strength of the enemy, who controlled the sea-shore. On the morning of the 25th of September the flank march began, through tangled forests, by the aid of the compass. It was a laborious task for the troops, especially since they had not regained their health from the ravages of the cholera in Bulgaria. Two days' march, however, brought the English army to the little port of Balaklava, on the south of Sebastopol, where the land and sea forces met. Soon after the allied armies had arrived at Balaklava, Saint-Arnaud was obliged by his fatal illness to yield up his command to Marshal Canrobert, and a few days later he died,--an unprincipled, but a brave and able man.
