Sidney Smith's sailors, with the brave Turks who rallied to their help, were not to be denied. Lannes' grenadiers were tumbled headlong from the tower, Lannes himself being wounded, while Rimbaud's brave men, who were actually past the breach, were swept into ruin, their general killed, and the French soldiers within the breach all captured or slain. One of the dramatic incidents of the siege was the assault made by Kleber's troops. They had not taken part in the siege hitherto, but had won a brilliant victory over the Arabs at Mount Tabor. On reaching the camp, flushed with their triumph, and seeing how slight were the apparent defences of the town, they demanded clamorously to be led to the assault. Napoleon consented. Kleber, who was of gigantic stature, with a head of hair worthy of a German music-master or of a Soudan dervish, led his grenadiers to the edge of the breach and stood there, while with gesture and voice--a voice audible even above the fierce and sustained crackle of the musketry--he urged his men on. Napoleon, standing on a gun in the nearest French battery, watched the sight with eager eyes--the French grenadiers running furiously up the breach, the grim line of levelled muskets that barred it, the sudden roar of the English guns as from every side they smote the staggering French column. Vainly single officers struggled out of the torn mass, ran gesticulating up the breach, and died at the muzzles of the British muskets. The men could not follow, or only died as they leaped forward. The French grenadiers, still fighting, swearing, and screaming, were swept back past the point where Kleber stood, hoarse with shouting, black with gunpowder, furious with rage. The last assault on Acre had failed. The French sick, field artillery, and baggage silently defiled that night to the rear. The heavy guns were buried in the sand, and after sixty days of open trenches Napoleon, for the first time in his life, though not for the last, ordered a retreat.
