General Gérard Leman was a Belgian Lieutenant general and fortification expert best known for commanding the defenses of Liège during the opening weeks of World War I. A graduate of the Royal Military Academy and an engineer by training, he oversaw modernization of Belgian forts and played a central role in early resistance to the German Empire's Schlieffen Plan. His decisions during the Siege of Liège (1914) made him a national figure, while his subsequent capture and imprisonment shaped debates about command responsibility and fortress warfare.
Born in Bauffe in Hainaut province, Leman attended the Royal Military Academy in Brussels where he completed officer training alongside contemporaries who later served in the Belgian Army. He pursued advanced studies in military engineering and fortification, engaging with contemporary works by military engineers associated with the French Third Republic and influenced by designs seen at Fort de Loncin, Fort de Maubeuge, and the precepts debated after the Franco-Prussian War. His formative education connected him to institutions such as the Brussels Military School and introduced him to doctrines circulating in Prussia, France, and the United Kingdom.
Leman's early service included postings in Belgian garrisons and staff roles at the Ministry of War in Brussels. Rising through ranks, he became an authority on permanent fortifications, working on the modernization of the National Redoubt and coordinating with engineers familiar with designs at Verdun, Namur, and Antwerp. He interacted professionally with figures such as Leopold II, and senior officers who served during the Second Boer War and observed fortifications in the Kingdom of the Netherlands and German Empire.
Promoted to senior commands, Leman supervised construction projects influenced by the work of military theoreticians associated with Alfred von Schlieffen, Ferdinand Foch, and observers from the Austro-Hungarian Army. His expertise brought him into correspondence with foreign military missions, engineers from France, staff officers from Russia, and defense committees in Liège province, linking him to civic authorities, municipal engineers, and rail planners from the Société nationale des chemins de fer vicinaux and the Compagnie des chemins de fer du Luxembourg.
As commanding officer of the Fortified Position of Liège, Leman directed the defense of the ring of forts around Liège, including Fort Loncin, Fort de Lantin, Fort de Hollogne, and Fort de Fléron. When the German 1st Army advanced under directives consistent with the Schlieffen Plan, Leman coordinated with Belgian field armies led by commanders such as General Félix Wielemans and municipal leaders of Liège city to delay the German Empire's timetable.
Under artillery bombardment employing heavy siege guns associated with the German Empire and industrial arsenals in Krupp, the forts, designed in part along lines similar to works at Séré de Rivières and influenced by experiences at Sedan, resisted for days beyond German expectations. Leman ordered countermeasures, directed infantry from units of the 3rd Division, managed liaison with the Belgian Army High Command and coordinated sabotage of railway lines to slow the advance through nodes like Liège-Guillemins station and the Meuse River crossings. The stubborn defense contributed to delaying the German Army and affected operations around Mons and the Battle of the Frontiers.
Following the destruction and collapse of several forts—most notably Fort de Loncin—Leman was wounded during the siege and ultimately captured by German Empire forces. He was transported to captivity in facilities where other high-profile prisoners such as officers from the Royal Navy and detainees from the Battle of Tannenberg were held. His captivity drew attention from international figures including representatives of the International Committee of the Red Cross and critics in the British press and French press who debated treatment of prisoners and the conduct of siege warfare.
Released at war's end, Leman returned to Belgium and lived in Brussels where he engaged with veterans' organizations and participated in discussions about post-war reconstruction, fortification policy, and memorialization. He observed developments at the Treaty of Versailles indirectly through Belgian delegation activities and influenced commemorations at sites like Fort de Loncin and municipal memorials in Liège. Leman died in Ixelles in 1920.
For his role at Liège, Leman received national honors including the Order of Leopold and the Order of the Crown, and was commemorated in monuments in Liège and military museums such as the Royal Museum of the Armed Forces and Military History. His name appears in historiography alongside commanders from the First World War like Helmuth von Moltke the Younger, Joffre, and Kaiser Wilhelm II in studies of early-war operations and the transformation of fortress design by heavy artillery manufacturers like Krupp and designers influenced by Raymond Adolphe Séré de Rivières. Leman's defense influenced Belgian military doctrine, discussions in the League of Nations era, and memorial culture in regions affected by 1914 combat.
