The Allied Bombing of German Cities in World War Two Was Unjustifiable

No one doubts the bravery of the thousands of men who flew and died in Bomber Command. The death rate was an appalling 44%. And yet until the opening of a monument in Green Park this year they have received no official recognition, with many historians claiming that the offensive was immoral and unj

Episode Summary

Executive Summary: This Intelligence Squared debate examined whether the Allied bombing of German cities in WWII was morally unjustifiable. Grayling argued area bombing was a war crime against civilians and later law confirms this; Bishop and Beevor stressed wartime necessity, context, and the campaign’s contribution to defeating Nazi Germany; Overy challenged its strategic value and highlighted alternatives. The audience ultimately shifted toward rejecting the motion.

Main Topics: Moral legitimacy of bombing civilians (Priority: 5/5): Grayling framed the issue as a moral one: even a justified war does not justify indiscriminate attacks on civilian populations. He argued that later international law codified what was already wrong. Wartime necessity and context (Priority: 5/5): Bishop and Beevor emphasized that decisions were made in existential wartime conditions, against a criminal Nazi regime, with Britain under severe pressure and few viable options. Strategic effectiveness and alternatives (Priority: 5/5): Overy argued the bombing campaign was a blunt instrument with weak evidence for its intended effects, and resources could have been better used for anti-submarine warfare, army support, and precision capabilities. Destruction vs military impact (Priority: 4/5): The panel debated whether city bombing materially shortened the war or mainly caused civilian deaths and destruction, with disagreement over damage to German industry, morale, and the Eastern Front. Historical hindsight vs contemporaneous judgment (Priority: 4/5): A major fault line was whether modern moral standards can be applied retrospectively. Opponents of the motion urged judging decision-makers by the information and pressures of the time. Law, precedent, and the evolution of warfare norms (Priority: 4/5): Grayling cited the Geneva Conventions and later prohibitions on indiscriminate attacks as evidence that the international community eventually rejected the practice, implying historical condemnation.

Key Arguments: Grayling argued that although bombing Hitler’s regime was justified, deliberately attacking civilian populations was not; the end does not justify the means. Grayling cited Thucydides, Hamburg, Dresden, and the later Geneva protocols to show that war corrodes judgment and that modern law now rejects area bombing. Bishop argued the audience must judge the campaign from 1942–45, when Britain faced likely German domination of Europe, the Holocaust, and limited military options. Bishop maintained that Bomber Command was the only direct means of striking Germany available to Britain at the time and that many Britons saw bombing as necessary retaliation. Bishop and Beevor both argued that bombing had military effects: forcing German air defenses to the Reich, affecting Eastern Front conditions, and contributing to shortened war duration. Overy countered that there was no strong prewar evidence that bombing would break morale or collapse industry, and that the RAF ignored lessons from Spain and the Blitz. Overy argued the campaign was strategically improvised and that resources might have been better spent on long-range anti-submarine patrols, fighter cover, tactical air support, or more precise bombing. Beevor argued the Luftwaffe and Nazi Germany had already normalized total war against civilians, making Allied retaliation understandable though not fully legally ideal. Beevor claimed strategic bombing helped by redirecting fighters and anti-aircraft guns away from the Eastern Front and by disrupting weapons production such as the Panther tank. Several speakers agreed late-war city bombing, especially after 1944, had diminishing military returns and became harder to justify morally and practically.

Data Points: Pre-vote support for motion: 83 - Audience members who initially agreed Allied bombing of German cities was unjustifiable Pre-vote opposition to motion: 136 - Audience members who initially opposed the motion Pre-vote undecided: 96 - Audience members who initially said they didn’t know Post-vote support for motion: 115 - Final vote count for the motion after debate Post-vote opposition to motion: 191 - Final vote count against the motion; motion defeated Post-vote undecided: 10 - Audience members still undecided after the debate RAF Bomber Command deaths: 55,000 - Grayling and others cited personnel killed in Bomber Command service Initial Cologne raid deaths: 469 - Bishop referenced the first 1,000-bomber raid on Cologne in May 1942 Hamburg firestorm deaths: about 45,000 - Grayling described deaths from Operation Gomorrah, mostly by suffocation UK civilian deaths in the Blitz: 43,000 - Overy cited this as the largest offensive against Britain German civilian and combat deaths from Allied bombing/war: 350,000 - Overy gave this as the death toll attributable to bombing campaigns Non-German civilians killed by Allied bombing in Europe: 70,000 - Overy’s closing statistic on civilians in France, Norway, Denmark, the Netherlands, and Belgium Aircraft accuracy from Butch report: 1 in 5 within five miles of target - Beevor cited Churchill’s alarm over RAF bombing inaccuracy in 1941 Soviet wartime casualties: 9 million servicemen and women killed; 15 million badly wounded - Beevor contrasted Soviet losses with Britain’s to explain strategic pressures German heavy anti-aircraft guns on Eastern Front by 1944: 1,200 - Beevor argued guns were withdrawn to defend the Reich Heavy anti-aircraft guns back in Germany: more than 7,000 - Beevor used this to argue bombing aided the Eastern Front by forcing redeployment Normandy 88mm guns by June 1944: 132 - Beevor linked air defense concentrations in Germany to reduced defenses in Normandy Bombing-related absenteeism in Germany: around 4% - Overy said bombing caused relatively little absenteeism compared with leave or illness Bombing-related absenteeism in heavy-hit UK areas: three-quarters or more back after 2–3 days - Overy cited Ministry of Home Security studies from Liverpool and other cities Germany’s industrial output during heavy bombing: could still expand considerably until September 1944 - Overy argued bombing did not critically undermine production

Pivotal Quotes: "If they are wrong now, they were wrong then." — Anthony Grayling: Grayling defended using later humanitarian law to judge the morality of bombing civilians "The moral expedient open to us was to lose the war against Hitler's Germany." — Richard Overy quoting a Lancaster navigator/official historian: Used to illustrate the wartime belief that abandoning bombing could be morally worse "We're fighting gangsters, so we've got to be gangsters ourselves." — Audience quotation cited by Patrick Bishop: Illustrated British public wartime attitudes toward retaliation and moral compromise

Implications: The debate shows how wartime necessity, moral principle, and strategic effectiveness can conflict. It also highlights why modern targeting law rejects indiscriminate bombing and why historical judgments remain contested when national survival is invoked.
