From the Missouri Message board:
Sanborn and McNeil led the attack on Independence, after which Winslow was brought up to pursue the retreating Confederates. Brown was not involved until the following morning, so it sounds as if the account you provide is actually referring to Winslow�s brigade, not Brown�s.
I don�t know if the following accounts will help you sort this out, but here you go:
�The Campaign in Missouri in September and October 1864�, by General John B. Sanborn, pp. 37-38, booklet housed at the Minnesota Historical Society--
"Col. Phelps, with his second Arkansas cavalry, held the advance and charged through gardens, door-yards, streets and alleys into the town so rapidly that all of the force before him had not time to get out of his way. He captured one of Gen. Cabell�s staff officers, the General�s sword, and a number of prisoners, and forced the enemy in his front to give way. Simultaneously the 13th Missouri Cavalry, formerly the 6th M.S.M., charged into the town at another part of the enemy�s line, carrying everything before them, sabering and pistoling those who resisted, capturing two guns of Hughey�s Arkansas battery, with caissons and horses complete, and making at least two hundred prisoners. Col. Merritt Young, of a rebel Missouri regiment, was killed in this charge.
�Driven out of the town, Fagan reformed his division, which was composed of three brigades, on the west bank of Stony Creek, and renewed the fight. As our forces were somewhat in disorder by reason of the charge we had made, and as it was now after dark, he was enabled to get his command in tolerable order, and moved against our right, with the view of turning our position in that quarter. But Winslow�s brigade struck his advancing line with the rush and force of an express train and drove it broken and bleeding from the field, towards the Big Blue. I was on the way with my brigade to meet the rebel advance, but before we could get to the desired position the main fight was over and the enemy in full retreat.�

�Pleasonton, who had, practically, been waiting for days to get Winslow�s experienced troopers in his front, now immediately ordered the brigade into action; and without stopping at Independence it rode on to the front. The 3d Iowa, being the head of the column, drove in the enemy�s rear guard and with the aid of the 10th Missouri, which made a vigorous dash upon his right, compelled Marmaduke who commanded the division, to dismount and face a new enemy, while he slowly yielded. Night came on, but Winslow pressed forward, with occasional volleys, and crowded Marmaduke into the river, though not then aware of that effect. Marmaduke�s report shows that he was in great trouble during the night between the necessities of constant defence at short range and of crossing the river in darkness. But, as the hills at this point are on the east side of the river and precipitous, there was no reaching the ford with artillery, and Marmaduke got over before morning.�
Perhaps regimental histories of the 3rd Iowa and other regiments in Winslow�s brigade might shed additional light.
