For his achievements the Austrians awarded Flies with the Commander's Cross of the Order of Leopold with war decoration on 21 August 1864.

Here he received orders from General Edwin von Manteuffel to lead a detachment consisting of five battalions with 8150 infantrymen, 225 cavalrymen and 22 guns to Gotha via Magdeburg and Halle.

The battle ended with a victory for the Hanoverians, but at this point they were surrounded by Prussian troops and, due to the supply situation, were no longer able to continue fighting.

[7] Flies was the main Prussian commander at the Battle of Roßbrunn which, despite earlier successes, eventually ended in a Bavarian victory.

Flies was retired on 7 January 1868 and awarded the 1st Class of the Order of the Red Eagle with oak leaves and swords on rings.

Flies married Therese von Schönfeld (born 27 April 1811 in Grimma; died 13 May 1882 in Wiesbaden) in Düben on 27 September 1832.
