Bombing of Nijmegen

Gotha mission cancelled

At 9:20^[5] in the morning of 22 February, 177 American B-24 Liberator bombers, escorted by dozens of fighters of the types P-38 Lightning, P-47 Thunderbolt and P-51 Mustang,^[7] took off from RAF Bungay airbase near the Suffolk village of Flixton.^[2] They flew in the direction of the German city of Gotha, where the Gothaer Waggonfabrik aircraft factory was producing Messerschmitt fighters and other Luftwaffe planes. This required a four-hour flight over German territory, making it an extraordinarily dangerous mission.^[2] If Gotha could not be reached, Eschwege was the next target, and if even that failed, the pilots had to seek out a target of opportunity in Germany by themselves on the way back to Britain.^[2]

Because the clouds were floating unusually high that day, the aircraft had trouble properly gathering into formation, and quickly lost sight of each other. Therefore, a considerable number of bombers already broke off their mission just 15 minutes after take-off and returned.^[2] Even while still above the North Sea, the Americans were unexpectedly fired on by German fighters.^[2] When the group passed by Nijmegen at 12:14 (CET), the air raid siren was activated by watchman Van Os, and the people of Nijmegen ran for cover in their shelters until the coast was clear.^[8] Shortly after, around 13:00 when the bombers had passed the Dutch–German border by about 10 miles, they received a message from command that the raid had to be cancelled due to too heavy cloud formations above Gotha for an effective bombardment; the units were recalled to England. Because Eschwege was still far out of reach as well, looking for targets of opportunity on the way back was now recommended.^[2]

Airstrike

It was an extremely difficult task to turn around hundreds of planes that had to stay in formation, leading to a huge chaos in the air and fragmenting the group into several squadrons who each sought their way back to Britain for themselves. Underway, they looked for targets of opportunity, and eventually the Dutch cities of Nijmegen, Arnhem, Deventer and Enschede were selected and attacked.^[2] The squadron flying to Nijmegen consisted of twelve Liberators of the 446th Bombardment Group, which were joined by two lost Liberators of the 453rd Bombardment Group.^[9] Beforehand, the flyers had been poorly informed about whether Nijmegen was a Dutch or a German city, whether German-occupied cities could or couldn't be bombed, and if so in what way, and they were negligent in finding out exactly which cities they were about to strike,^[3] partly due to miscommunication that can be ascribed to technical problems such as a stuck radio operator's morse key.^[2]

Watchman Van Os had given the clear sign at 13:16.^[8] For reasons that are still unclear, he failed to activate the air raid siren a second time as soon as 14 of the aircraft returned in Nijmegen's airspace, mere minutes after the clear sign had been given,^[8] causing citizens not to run for cover as quickly as possible in time on this occasion.^[2] Van Os stated afterwards that he did not ring the siren a second time until he heard explosions coming from the city centre.^[8] At 13:28,^[10] 144 brisant bombs (each weighing 500 pounds) and 426 shrapnel shells (20 pounds a piece) were dropped.^[9] The actual target of opportunity, the train station terrain, was successfully hit. However, a considerable part of the bombs fell on the city centre in residential areas, destroying homes, churches and other civil targets, killing hundreds of innocent and unarmed civilians.^[3] After the fact, official Allied sources claimed that the pilots thought they were still flying above Germany, and had misidentified Nijmegen as the either the German city of Kleve (Cleves) or Goch. Yet some flyers themselves stated just an hour after landing in England that they had bombed Nijmegen, and a navigator even reported this in the air moments after the raid.^[3]

Allied and German reactions

Nazi propaganda trying to exploit the tragedy: 'With friends like these, who needs enemies!?'

The Nazis reported that the Dutch government-in-exile in London had given permission for the airstrike on Nijmegen, and that it therefore was an intentional bombardment.^[2] They made passionate attempts to exploit the bombing for propaganda: in public places, posters were hung with texts such as 'With friends like these, who needs enemies?' and 'Anglo-American Terror'. The German-controlled newspapers furiously rebuked the Allies and the Dutch government-in-exile as well, one remarking "The Anglo-American pirates of the sky have once again executed the orders of their Jewish-Capitalist leaders with extraordinarily positive results". However, it looks like the propaganda was ineffective: seven months later, the American ground troops were welcomed as heroes by the inhabitants. Internal sources of the occupying government's Department for Popular Education and Arts even suggest the propaganda may have been counterproductive.^[2]

Immediately on the next day, the Allied airforce launched an investigation: all air raids planned for that day were cancelled (also due to poor weather conditions), and all flyers and briefing officers involved were held put on the base and questioned.^[11] The full scale of the disaster was not yet clear on 23 February, but American aerial photographs taken during the attack, that Dutch naval commander Cornelis Moolenburgh managed to obtain via the Royal Air Force, left no doubt about the fact that Nijmegen (and especially civilian targets in its centre), Arnhem and Enschede had been hit. Molenburgh informed Dutch ambassador Edgar Michiels van Verduynen, who confronted American ambassador Anthony Joseph Drexel Biddle, Jr. (until then ignorant of the events) on the matter in the presence of Dutch queen Wilhelmina. Biddle quickly informed U.S. President Roosevelt. American air force commander Henry H. Arnold was irritated when he discovered that the Dutch embassy had been informed earlier than he himself, and he henceforth denied Moolenburgh access to USAAF documents via the RAF (which Moolenburgh could however still obtain via secret service officer Kingman Douglass). The USAAF also refused to send out reconnaissance aircraft for taking photos assessing the exact damage in the three cities, whereupon the RAF offered and executed this task.^[12] Wilhelmina demanded and received a written statement on what had happened, although it is unclear what it said.^[11]

The American army command was relatively late in drawing lessons from the disorderly conducted air raid, which had struck an ally's civilian population hard. Not until mid-May 1944, orders were given to seek out targets of opportunity at least 30 kilometres away from the Netherlands' border.^[3]

Brinkhuis (1984)

At last, amateur historian Alfons Brinkhuis, who as a 10-year-old boy had experienced the bombing of Enschede on the same day, became the first person to conduct an elaborate investigation into the archives, and interview dozens of eyewitnesses. In the summer of 1984, he published his conclusions in De Fatale Aanval 22 februari 1944. Opzet of vergissing? De waarheid over de mysterieuze Amerikaanse bombardementen op Nijmegen, Arnhem, Enschede en Deventer ("The Fatal Attack 22 February 1944. Intent or Error? The Truth About the Mysterious American Airstrikes on Nijmegen, Arnhem, Enschede and Deventer"). In doing so, he broke a taboo, and many facts were brought out in the open for the first time, although some of his research has been rendered obsolete by later findings. Brinkhuis' 7 conclusions were:^[14]

1. Hundreds of bombers were unable to gather due to the high cloud formations, and had to cancel their mission prematurely.
2. Formation of the attack group was not completed yet before German fighters carried out an unexpected counterstrike above the North Sea.
3. Miscommunication occurred due to poor weather conditions, the American Mandrel radar jammer and especially the stuck morse key, preventing most aircraft from sending verifiable messages to the bases (vice versa was still possible, however).
4. Because of this miscommunication, some units received the recall sooner than others, and they themselves therefore had to choose targets of opportunity far outside the normal routes.
5. Because of the wind, planes were driven more to the west without realising it (the clouds prevented them from seeing above which country they were flying).
6. The Norden bombsights were set on Gotha as the target; there was no time to reprogram them, making precision bombing impossible.
7. Navigators always flew based on schedules; they were not trained to orientate themselves based on the landscape. This enabled flyers to get lost when missions weren't going according to plan.

Rosendaal (2006–09)

In 2006, history docent Joost Rosendaal of Radboud University Nijmegen started a new study into the bombardment,^[15] which was eventually published in 2009 as Nijmegen '44. Verwoesting, verdriet en verwerking ("Nijmegen '44: Destruction, Grief, and Consolation". In it, he classified the attack as an opportunistic bombing rather than an error. Rosendaal rejects the notion of an 'error', because the Americans were negligent in properly identifying which city to bomb. The Americans "intentionally bombed a target of opportunity, which, however, had not been unambiguously identified."^[3]

Rosendaal added that the death toll was further increased by several disastrous circumstances. The switchboard operator, who normally directed emergency services, was killed during the raid, and without her communications went much slower. Many water pipes had been destroyed, making firefighting efforts much harder and more time-consuming. Dozens of people were still alive, but stuck under the rubble; many burnt to death when spreading flames reached them before they could be extinguished.^[3]
