Realizing he had been <unk> and that <unk> 's troops were tiring rapidly , <unk> sent orders to <unk> 's division to <unk> forward . By mid @-@ morning the French momentum had stalled ; <unk> committed most of his remaining forces to driving <unk> back , leaving a single <unk> 300 <unk> cover his northern flank , and sent the rest to attack the Russian right .

His 4 @,@ 500 French opposed 2 @,@ 600 Russians and forced them back toward Stein while pressing an attack along the river . <unk> had no option , for neither <unk> 's nor <unk> 's flanking columns were to be seen .
