Afghan forces on August 28. Heavy engagements lit up in the first week of September. A tactical victory was scored when German forces managed to rout a Taliban party from a battlefield in Imam Sahib. Eleven insurgents were killed and four wounded in action, but so were four Germans. Eight armoured fighting vehicles were lost to hostile fire. Kunduz airstrike On September 4, a devastating nighttime air raid struck a riverbank only 7 kilometres to the southwest of Kunduz. Taliban militants had hijacked civilian supply trucks with gasoline on a nearby road. After an attempt to bring the heavy vehicles across the Kunduz river had failed, the insurgents sent for nearby villagers to come and help unload the fuel. The German command center was aware of the incident, readied a quick reaction force and sent for close air support. Unbeknownst to them a considerable number of civilians had mixed with the insurgents and militant supporters in order to come by a free gallon of fuel. Fearing a truck bomb attack could be imminent if the trucks came unstuck, a German commander ordered a pair of American F-15s to attack the scene with bombs. A later German investigation concluded the attack caused up to 142 deaths, including an unknown number of civilians. The attack, though justified by several officials, caused considerable uproar in Germany and led to the resignation of senior officers and the Minister of Labour Franz-Josef Jung in October 2009. The German officers who orchestrated the bombing were later acquitted of all charges. German courts denied civilian casualties any form of compensation on the grounds that the involved military personnel were led to believe by a double agent among the insurgent party that no civilians were present at the scene. Three German troopers were wounded in a vehicle-born suicide attack the following day. A further week-long series of engagements resulted in eight more German WIAs, among them the first female German soldier to be wounded in action. KSK operatives launched another successful raid in early October and captured 15 Taliban during a surprise attack. Three civilians were killed and 17 wounded during a Taliban attack on October 3. Six insurgents were detained by ISAF and ANSF forces on October 10 and more than 50 surrendered. One insurgent was killed when hostile forces attacked German soldiers during a humanitarian mission on October 20. A day later, two Taliban were killed
