On the evening of December 4, 1944, 282
Lancaster bombers of 5 Group and ten Mosquito
Pathfinder aircraft flew over the city in loose formation. The night was thickly clouded, this factor altered the approach height of the planes. At 7:18 the first plane flew over, but it was the second plane that dropped 10 bombs with long-term fuses onto the city about one minute later. Immediately after dropping the bombs, this plane began its return flight. At 7:20,
flare markers were dropped on the city in order to allow accurate bombing by the rest of the squadron. A 'flashlight bomb' was dropped, and exploded at 200 metres. After all the flares were released, the area was illuminated as bright as day. This light was clearly distinguishable to the bomber pilots, and they were subsequently ordered to go in and assault. After the flare markers, the flashlight bombs, and other such devices used for targeting were released and were functioning effectively, Lancaster PB 251s dropped the first load of high explosives. Approximately 5,800 bombs, dropped from a height of 3,800 metres, hitting the city at 7:29. The attack continued until 9:38, with a further 1,200 tonnes of bombs released upon the city, and 380 devastating the marshalling yard. Within a period of half an hour, over 6,500 people, including 1,000 children under 10 years of age, lost their lives. The exact number of victims is impossible to determine because many corpses were burned beyond recognition. Due to the number of
incendiary bombs that fell on the city, and the number and impact of the bombs, fires burned throughout the night, entering the city was impossible for days.
Aftermath Although 62% of the city was destroyed, the damage in relation to the number of bombs and the force of the attack is remarkable for several reasons. Many German cities and towns were already in ruins, or were burnt-out by prior bombardments; the British would have preferred to attack with high explosive bombs in order to maximise the damage caused. The entire old section of the town was destroyed. Donations to the city were instrumental to the city's repairs and victim aid. During the actual attack, German defenses could do little. Two anti-aircraft positions at the Neckar and 14 German
Junkers Ju 88 night fighters fought against the British bombers. The RAF lost eleven aircraft. Since the bombing was conducted on a Monday evening, much of the
population of Heilbronn was positioned in or around the city center, but at the first signs of attack, many fled to a high bomb shelter (the General Wever tower), and two other low shelters (in the industrial area and at
Kaiser Friedrich-Platz). Many also fled to an air raid shelter nearby. However, by 8:00 pm the city centre was engulfed in flames, and anyone inside these buildings either burned to death or were asphyxiated. Many people who attempted to leave the city were also burnt on the roads. In the end, the air raid shelter collapsed, anyone left inside was killed. To make matters worse, the urban hospital was left in ruins, so it was nearly impossible to treat the wounded. A great many people were able to take refuge in the emergency military hospital, or a converted mental hospital located in nearby Weinsberg. After the fires were under control, rescue work and clearing up of the town began and help was sought from the surrounding area. On the night of 5 December the number of dead was stated to be approximately 4,000 with another 3,000 injured.
Burials A task force was chosen to find the dead and to rescue any bodies. The dead that were found were brought to the city
cemetery. Even then, there were not enough coffins for all the dead, Ulm and other cities supplied a total of 1,000 caskets. When it was found that the cemetery, as well as other places, could not provide enough space to adequately lay to rest the deceased, the resolution was that an honor cemetery (mass grave) be built at the edge of the forest near the valley of the Köpfer Creek. The work on this project began on 6 December, while the dead were brought on carriages to the Köpfer Valley. On 8 December, the burnt-out city center and the collapsed air raid shelter were accessed by salvage teams, and more dead were returned to the families for burial. Salvage work continued for over three weeks, into the Christmas of 1944. Many dead could not be retrieved, particularly in heavily damaged road courses. Many would simply have been impossible to locate or bring out, whether from the air-raid shelter, or the ruins of the city center; it is assumed that there are many human remains still in the soil. ==Attacks until the end of the war==
