7 April

In the early hours of 7 April, three Blenheims of the Yugoslav 8th Bomber Regiment took off from Rovine to bomb the railway junction at Feldbach, but became disoriented in bad weather. Only one aircraft found a target, bombing a bridge and road near Steyr before continuing on to Wiener Neustadt where it was hit by anti-aircraft fire and made an emergency landing. Over the period 7–9 April, LI Infantry Corps held the lead elements of the 183rd and 132nd Infantry Divisions back to some extent while the rest of each division de-trained in Graz and made their way to the border. German forces along the front of the 7th Army continued to push towards Maribor and Dravograd on 7 April, against significant resistance from the 6th, 7th and 8th Border Regiments. The German thrusts towards Maribor broke through the Yugoslav defensive line Pesnica–Lenart–

On the afternoon of 7 April, Trifunović again pressed Petrović to order a withdrawal from the border.

At 19:30, the Yugoslav Supreme Command advised Petrović that he had approval to withdraw endangered units on the right wing of the 7th Army. Morale in the 7th Army started to decline due to fifth column elements encouraging soldiers to stop resisting the enemy.


8 April

On the night of 7/8 April, Petrović ordered Trifunović to begin to withdraw, first to a line through the Dravinja river, Zidani Most bridge and the right bank of the Krka river. Later in the day this was moved back to the line of the

Disregarding orders from above, Palten exploited their withdrawal by leading his ''kampfgruppe'' south towards the town, and crossing the Pesnica river in

For disregarding orders, Palten and his ''kampfgruppe'' were ordered to return to Spielfeld, and spent the rest of the invasion guarding the border. In the meantime, the forward elements of the two divisions consolidated their bridgeheads, with the 132nd Infantry Division securing Maribor, and the 183rd Infantry Division pushing past Murska Sobota, reaching Kapelski Vrh. Some bridges over the Drava were blown before all elements of the 7th and 8th Border Regiments had withdrawn, but some soldiers were able to swim across, the rest being captured by the advancing Germans.

9 April

On 9 April, the Germans continued their advance, and all elements of both divisions of LI Infantry Corps had finally unloaded in Graz. In the meantime, the 7th Army continued rapidly withdrawing its right wing, while withdrawing its centre more slowly. The 38th ID continued to withdraw south from Ptuj through Krapina towards Zagreb, while the Mountain Detachment ''Triglavski'' on its left flank fell back to the southern bank of the Krka river. Units of LI Infantry Corps crossed the Drava along the line Maribor–Ptuj and further east, and continued to expand their bridgehead south of Maribor. Elements of XXXXIX Mountain Corps expanded their bridgehead at Dravograd. German aircraft again attacked airfields in the rear area of the 7th Army. As the activities of Natlačen and his NszS were continuing, the Yugoslav Supreme Command ordered their arrest. Rupnik and the head of the operations staff of the headquarters of the 1st Army Group, ''Pukovnik'' Franjo Nikolić, who were both Slovenes, hid the orders from Petrović and did not carry them out.

Chaos ensued throughout the 7th Army, whose Croat and Slovene soldiers could hear fifth column radio broadcasts telling them of their pending encirclement by the Germans and encouraging them to return to their homes and not fight against the invaders. This was reinforced by Natlačen and his NszS, who had distributed leaflets on the night of 10/11 April urging soldiers not to resist the Axis troops. To maintain public order, the NszS also formed a "Slovenian Legion" on 11 April, and encouraged Slovene nationalists among the 7th Army to join it. This force, split into a dozen units and totalling 2,000–3,000 men, then began to assist the Germans in disarming units of the 7th Army, but did not engage in combat with Yugoslav troops. The NszS authorised Natlačen to negotiate with the Germans for the creation of a Slovene client state along the lines of the NDH and the Slovak Republic, and Natlačen appointed the Ljubljana police chief to make contact with the Germans.
