 The 2nd Panzer Division (XVIII Mountain Corps) entered Yugoslavia from the east on the morning of 6 April and advanced westward through the Struma Valley. It encountered little resistance, but was delayed by road clearance demolitions, mines and mud. Nevertheless, the division was able to reach the day's objective, the town of Strumica. On 7 April, a Yugoslav counter-attack against the division's northern flank was repelled, and the following day, the division forced its way across the mountains and overran the thinly manned defensive line of the Greek 19th Mechanized Division south of Doiran Lake. Despite many delays along the mountain roads, an armoured advance guard dispatched toward Thessaloniki succeeded in entering the city by the morning of 9 April. Thessaloniki was taken after a long battle with three Greek divisions under the command of General Bakopoulos, and was followed by the surrender of the Greek Eastern Macedonia Army Section, taking effect at 13: 00 on 10 April. In the three days it took the Germans to reach Thessaloniki and breach the Metaxas Line, some 60,000 Greek soldiers were taken prisoner. The British and Commonwealth forces then took over the defence of Greece, with the bulk of the Greek Army fighting to maintain their old positions in Albania.
