Hunerbein, coming from the right, had retaken Bausk, and on the 30th Yorck made a general advance, driving Steingell back all along the line. The fighting was not at all severe, Steingell merely gave way deliberately before the advance of Yorck’s now superior columns. On the other hand, Yorck was probably not anxious to do more than his strict military duty required. Steingell retired towards Riga with no serious loss and re-entered the lines on the 2nd of October, Essen at the same time evacuating Mitau. The losses on neither side were heavy. The result of the action was that Macdonald decided to come himself to the support of Yorck. Leaving a Polish regiment in Dünaburg he marched for Mitau with the rest of Grandjean’s division, but when he arrived the Russians had retreated into Riga. The Marshal increased Hunerbein’s brigade to 8 battalions, rearranged the positions of the troops, and sent Grandjean with one brigade back to Illuxt, near Dünaburg. To draw closer to Riga with his feeble forces was evidently impossible, and week after week wore itself away without any fighting except some occasional skirmishing at the outposts. After his victory at Polotsk, on August 18th, St. Cyr had been unable to follow in pursuit of Wittgenstein owing to his weakness in cavalry fit for the purpose. Wittgenstein therefore was able to withdraw unmolested behind the Drissa. On the 22nd Wrede made a strong reconnaissance towards Sivokhino, but the Bavarians were repulsed by a detachment under Colonel Vlastov with a loss of about 300 killed and wounded and 150 prisoners. Both sides now settled down into cantonments. Both had suffered very severely and neither was in a state to resume hostilities. Wittgenstein entrenched his position at Sivokhino, and his cavalry were able to circumscribe the French foraging operations on the right bank of the Düna. Wittgenstein also fortified his advanced base of Sebezh. Meanwhile, St. Cyr threw up entrenchments round Polotsk. The troops were distributed around the town, and, being largely in quarters or in barracks and tolerably well supplied, were soon in good condition. The effectives were increased by drafts and convalescents, but it is doubtful whether there was any great rise in the numbers owing to the diminution occasioned by constant petty skirmishing. The Bavarians were apparently unable to recover from the blighting effects of the sickness planted in their midst by their terrible hardships in July, and, though they were at rest and better supplied than they had hitherto been, their numbers continued to diminish. Maret and Hogendorp did their best to forward supplies from Vilna, but bread was often scarce and already, on October 7th, St. Cyr was writing to express his anxiety at the difficulty of procuring forage. The numerical strength of St. Cyr’s force by the middle of October appears to have been about 30,000 men--2nd Corps 21,000; Doumerc about 2200; 6th Corps perhaps 7000 or 8000.
