On 27 May 1942, Heydrich planned to meet Hitler in Berlin. German documents suggest that Hitler intended to transfer him to German-occupied France where the French Resistance was gaining ground. To get from his home to the airport, Heydrich would have to pass a section where the Dresden-Prague road merges with a road to the Troja Bridge. The junction in the Prague suburb of Libeň was well suited for the attack because motorists have to slow for a hairpin bend. As Heydrich's car slowed, Gabčík took aim with a Sten submachine gun, but it jammed and failed to fire. Heydrich ordered his driver, Klein, to halt and attempted to confront Gabčík rather than speed away. Kubiš, who had not been spotted by Heydrich or Klein, threw a converted anti-tank mine at the car as it stopped. It landed against the rear wheel. The explosion ripped through the right rear fender and wounded Heydrich with metal fragments and fibres from the upholstery causing serious damage to his left side: he suffered major injuries to his diaphragm, spleen, and one lung, as well as a broken rib. Kubiš received a minor shrapnel wound to his face. After Kubiš fled, Heydrich ordered Klein to chase Gabčík on foot, but Gabčík escaped after he shot and wounded Klein.
