the 1790 version. The village was renamed Abancourt-la-Montagne after the French Revolution. Between 1791 and 1823, the commune was reattached to Romescamps. In 1823 Abancourt was newly created as a commune from Blargies with Hennicourt added to it. In 1867 the railway came to Abancourt with the construction of Abancourt Station on the Rouen to Amiens line. It was connected directly to Le Tréport and Paris in 1873–1875. In the First World War the main British supply ports of Le Havre and the inland port of Rouen had restricted hinterlands. It was necessary to find a location where the daily supplies, to maintain 1.3 million troops, could be marshalled and distributed. Abancourt, the junction of several key railway lines to the coast and the Somme, was chosen. Supply trains from Le Havre and Rouen disgorged their content into vast warehouses in the Abancourt complex along of track. The warehouses contained enough non-perishable stores to last at least one month and dispatched twenty-two supply trains a day to the next distribution station. Today there is no obvious trace of this vast complex of warehouses and sidings. In the First World War, the British Army had a prison at Abancourt. In August 1916 a serious mutiny broke out in the prison, for which seven ring-leaders were prosecuted and at least two put to death on 29 October 1916: British Gunner Lewis, aged 30, shot at Rouen, and New Zealand Private John (Jack) Braithwaite, 35 years old, shot at the prison.<ref>[http://www.teara.govt.nz/en/biographies/3b44/braithwaite-john Braithwaite, John Biography], Ian McGibbon, Dictionary of New Zealand Biography, Vol. 3, 1996</ref> World War II See Heraldry Administration Mayors Intercommunality Abancourt is a member of the Community of communes of Picardie Vert, which comprises the communes of Formerie, Grandvilliers, Marseille-en-Beauvaisis, and Songeons.
