Originally something I posted on another forum in a debate about revolves vs sabers... but all of it are cases of union cavalry using mounted charges as a way of winning a fight.
All of it are about the battle of mine creek. reports from different union officers.
Here is what Col. John L. Beveridge, Seventeenth Illinois Cavalry wrote in is report.
"On the 25th, after the battle of Mine Creek, when the brigade was ordered to the front, the regiment occupying the center of the column in the order of march, where the ground would permit by doubling up the column, was ever at the front, and made one gallant charge upon the enemy with sabers drawn, in column of squadrons. The enemy did not wait to receive the charge and no damage was done to either party."

Major Abial R. Fierce, Fourth Iowa Cavalry
My regiment had just formed on the extreme left of our line when I commenced the charge. The three companies on the right of my regiment charged through the line of the Tenth Missouri Volunteer Cavalry Regiment, which was formed in their front. In that charge we crushed the enemy’s right completely. We pressed them so close that I cut eight rebels from their horses with my own saber. My regiment captured over 200 prisoners with two stand of colors.

(he is complaining earlier in the report that his unit don't get sufficient credits for the victory... so I would take his claim with a grain of salt.)
Colonel Chas. W. Blair 14th Kansas cavalry
The head of the column was here checked by a heavy fire from the field, and it was evident that another battle was to be fought. Accordingly the general formed his brigade in close column of companies, and made them a little speech while forming to the effect that it made no difference whether there were 1,000 or 10,000 men on that field, he wanted them to ride right over them and saber them down as fast as they came to them. The men responded with a yell, the dismounted skirmishers tore down the fence in the face of a galling fire, and the column swept through it like a tornado.

To be fair one officer Col. John F. Philips, commander of the 1st cavalry brigade wrote:
My brigade was precipitated on the enemy’s center and left with tremendous energy, when the fighting became general and terrific. The impetuosity of the onset surprised and confounded the enemy. He trembled and wavered and the wild shouts of our soldiers rising above the din of battle told that he gave way. With pistol we dashed into his disorganized ranks and the scene of death was as terrible as the victory was speedy and glorious. Major-General Marmaduke, Brigadier-General Cabell, some colonels, several line officers, four guns, one stand of colors, and a large number of prisoners were captured by this brigade.

What is clear is that the union cavalry after using dismounted skirmishers in the opening part of the battle to clear fences, won the battle by a direct mounted charge... where sabers was very clearly used very effectively.
