Through the Iron Bars: Two Years of German Occupation in Belgium

In Short

Written after twenty-seven months of World War I, this work offers an urgent contemporary account of occupied Belgium under German rule. Emile Cammaerts documents the shift from initial military conquest to a systematic campaign of economic exploitation, civic suppression, and forced labor. The text details how public morale endured despite severe censorship, the destruction of infrastructure, and mass deportations. By combining administrative evidence with vivid anecdotal accounts, Cammaerts captures a pivotal historical moment. The book remains a poignant testimony to civilian resilience and the moral stakes of wartime occupation.

The Story

The narrative begins in the autumn of 1914, following the initial defense of Liège and Antwerp. While the Belgian army under King Albert maintains a foothold on native soil along the Yser, the civilian population behind enemy lines is enclosed behind metaphorical prison gates. In the early weeks, German authorities maintain a facade of tolerance in major cities like Brussels to prevent unrest along fragile lines of communication. Civilians draw fleeting hope from Belgian troop sorties and improvise public displays of solidarity.

This temporary leniency vanishes as the front stabilizes. The occupying authority shifts to treating Belgium as a conquered domain intended for permanent integration into the German Empire. National symbols are outlawed: displaying the tricolour cockade becomes a crime, patriotic songs like the Brabançonne are banned from schools, and public celebrations of King Albert's feast day or Belgian Independence are prohibited. The occupyng administration systematically strips the country’s wealth, levying exorbitant monetary contributions and seizing agricultural yields, livestock, and industrial equipment.

As the British naval blockade cuts off raw materials, Belgian manufacturing grinds to a halt. In response to high wages offered by German factories, Belgian workers initiate a wide-scale patriotic strike, choosing severe poverty over contributing to the enemy's war effort. To break this impasse, Governor-General von Bissing issues a series of increasingly stringent decrees designed to legitimize forced labor. These measures culminate in the mass deportations of late 1916, where tens of thousands of able-bodied men—regardless of employment status—are rounded up and transported to Germany or forced to build military infrastructure on the Western Front.

Simultaneously, the administration attempts to divide the nation by exploiting historical tension between Flemings and Walloons. The German state forcibly converts the University of Ghent into a Dutch-speaking institution to curry Flemish favor. This strategy fails as Flemish leaders reject the overture, leaving the university deserted by legitimate students and boycotted by the local population.

When Germany proposes peace negotiations around Christmas 1916, Cammaerts frames the gesture as a calculated political maneuver designed to exploit civilian suffering and weaken Allied resolve. He concludes that true peace cannot be accepted on terms set by an occupying force that continuously violates international treaties. The text closes with an affirmation that Belgium’s fate remains inextricably bound to the Allied cause and its commitment to ultimate restoration.

How It Unfolds

The prison gates close The occupied population is cut off from the outside world following the fall of Antwerp and the withdrawal of the national government. In Brussels, early attempts to intimidate the public by parading wounded Belgian prisoners backfire when citizens successfully spirit the captives away from their escort.

Symbols of the state suppressed Occupying forces ban national flags, patriotic songs, and official celebrations, attempting to break civic morale. The population responds with quiet defiance, concealing patriotic ribbons in their clothing and adopting the defiant words of local leaders as passwords of resistance.

The nation's wealth dismantled The military administration systematically requisitions livestock, crops, and manufacturing machinery while imposing massive financial levies. Industrial production halts as half a million workers refuse to work for the occupying power, leading to widespread reliance on international food relief.

Legislation turns to conscription Governor-General von Bissing issues successive decrees that penalize unemployment, strip local courts of jurisdiction, and empower military commanders to direct labor by force. These legal steps lay the groundwork for the wholesale deportation of Belgian workers.

Raids sweep the communes In late 1916, military patrols round up tens of thousands of citizens from towns across Belgium, disregarding employment status and seizing relief workers alongside laborers. The deportees are sent to forced labor camps or driven to construct strategic military railways behind the front lines.

The peace initiative rejected The German offer of an armistice in late 1916 is characterized as an attempt to leverage the plight of deportees against Allied resolve. Belgian civic and religious leaders reject the proposal, asserting that no peace can exist without full restoration and justice.

The People

• King Albert serves as the moral center of Belgian resistance, leading the remaining national troops on the Yser front. His refusal to sign a separate peace keeps the government aligned with the Allies and provides a unifying figurehead for the occupied population.
• Governor-General von Bissing represents the supreme German administrative authority in Brussels. He attempts to balance public order with economic exploitation, enacting the decrees that legalize forced labor while seeking to divide Flemings and Walloons.
• Cardinal Mercier acts as the primary spiritual and vocal defender of civilian rights within the occupied territory. Through pastoral letters and formal protests to German leadership, he denounces the deportations and rallies the population's moral resolve.
• Burgomaster Max embodies municipal resistance in Brussels. His public refusals to comply with arbitrary German commands establish a standard of civic defiance before his eventual arrest and imprisonment.
• The Belgian Worker represents the collective resistance of the laboring class. By maintaining the "strike of folded arms," hundreds of thousands choose hunger and the threat of deportation over manufacturing war materials for the occupying army.

In Its Own Voice

"Up to the beginning of October, the Belgians, and specially the people of Brussels, had been kept in a state of suspense by the three sorties of the Belgian army..."

This passage reflects the initial period of uncertain hope in late 1914 before total isolation settled over the capital.

"In face of the common danger, all these differences would lose their hold on the people's soul, that the former bitterness of their quarrels was nothing compared with the sacred love of their country which they shared."

Cammaerts explains how pre-war political and linguistic divisions dissolved under the shared experience of foreign rule.

"By the waters of Babylon, there we sat down, yea, we wept, when we remembered Zion."

The author cites the biblical text chosen by Cardinal Mercier to articulate the grief and patriotic devotion of a captive population.

What It's Really About

The text addresses the conflict between international law and total military necessity. Cammaerts examines how an occupying power uses state bureaucracy to transform illegal acts into legal structures, systematically dismantling a nation's economy under the guise of administrative necessity.

Beyond the legal debate, the book considers the nature of national identity under total suppression. It argues that a nation's core strength lies not in its physical institutions or military power, but in the shared moral commitment of its citizens. The author illustrates how political, social, and linguistic factions can unite when fundamental liberties are threatened. Ultimately, the work asserts that forced compliance cannot break a population's internal sovereignty, framing passive resistance as a vital form of defense.

Why Read It Today

This work offers a raw, contemporaneous view of life under military occupation written while the ultimate outcome of World War I remained uncertain. Free from hindsight, Cammaerts captures the immediate psychological strain, administrative friction, and moral dilemmas experienced by civilians living behind enemy lines. Readers interested in military history, political ethics, and human rights will find a meticulously documented case study in how modern states manipulate legal frameworks to justify oppressive measures.

The reading experience is direct, structured, and shaped by the urgency of wartime advocacy. Cammaerts writes in clear, measured prose that balances official statistics and legal analysis with human detail. While the book reflects the intense patriotic passion and explicit anti-German stance of a 1917 Allied publication, its rely on official decrees, pastoral letters, and specific local reports gives it enduring historical value. It stands as a vivid account of civilian endurance under extreme adversity.
