The 300th launched a second attack at 2330 hours with its greatly diminished resources, but this again was stalled by Soviet artillery fire with heavy loss. Attempts at relief involving some heavy fighting resumed on the 21st, as these extracts from the radio log show:
From II 0832 To Armoured Artillery Regiment ‘Kurmark’: from Forward Observer, 2nd Battery. Possibility exists that codes have been blown. Use new codes.
From II What is the situation?
To II New countermeasures being prepared.
From II 0935 To Commanding Officer 300:
1) Enemy is digging in from direction of WUHDEN in a second trench running from the shot-up Panther to here from the direction of the main road. Thus there is a danger that this trench will eventually lead to the track and form a second continuous trench between you and us.
2) Fire direction is being tried via tank, as own set is u/s.
2) Request permission to fire upon identified heavy weapons.
The ODER is clearly visible.

From II 1218 To Regiment: Request urgent running harassing fire on SPERBER, EMIL, DROSSEL by all available artillery resources.
To II Still no orders from Corps.
There followed recommendations for the award of the Iron Cross First Class for six officer cadets, and Second Class for a further 38 officer cadets, 26 other ranks and eight Volkssturm men, the promotion of Second Lieutenant Heinrich to lieutenant and Gunner Brandenburg to bombardier for his outstanding conduct as a radio operator under the heaviest enemy fire.
All the while Colonel Willy Langkeit, the ‘Kurmark’ divisional commander, was doing his utmost to get permission from the XIth SS Panzer Corps commander, the fanatical Nazi SS-General Matthias Kleinheisterkamp, to give permission for the garrison to break out, but so far without success.
