context_page_description: The Year XI system was a French artillery system developed during the rule of Napoleon. The Year XI system was original in that it brought various improvements to the highly successful Gribeauval system, on which many successes of the Napoleonic Wars relied. It especially consisted in streamlining the existing Gribeauval designs. The main proponent of the new system was General Marmont. It was superseded by the Valée system.
context_section_description: The Year XI system would be further improved with the Valée system in 1828.
