The Axis have completed converting the rail line as far as Sumy and so should be able to get their supply situation under control. The remaining panzer divisions made a push to the north of Kharkov (big red line), but are now wary of massed Soviet forces on their flanks (circled in black). To the south Axis infantry made a few successful probes. The Soviet lines look extensive, but they are only weakly held.
In the centre the Axis made an initial attack on the Dnepropetrovsk pocket and the Soviets were very unlucky to have two of their key positions surrender (which I've marked with an X). The Axis need to liquidate this pocket quickly as the troops are much needed elsewhere.
Down south things got a bit more interesting. The Axis captured Zaporozhe and then started to try and get round the northern flank of the Soviet forces. The Soviets realising how weak the Axis will be as they withdraw troops to the Crimea, reversed their retreat. The Axis supply situation down south is not good
