On 25 June 1794, Moreaux was named commander of the
Army of the Moselle, taking over from
Claude Ignace François Michaud. In July his army captured
Trier and on 23 October it captured
Koblenz. One of Moreaux's divisions led by Rémy Vincent captured
Rheinfels Castle on 2 November leaving only Mainz and
Luxembourg City in enemy hands on the Rhine's west bank. While Michaud's
Army of the Rhine received instructions to lay siege to Mainz, Moreaux was ordered to make preparations to capture Luxembourg. The fortress had served the
Habsburg Austrians as a major supply base during their military operations against France. Seizing Luxembourg was expected to yield enormous stocks of accumulated military supplies. Since the nearest enemy army was far away on the opposite bank of the Rhine, there was little risk that the Allies might relieve the city. For this mission, Moreaux assembled 19,800 soldiers in the divisions of
Jean-Jacques Ambert, Jean-Baptiste Debrun and Guillaume Péduchelle. These were formed into two columns, including one under Debrun which approached on the Liège road starting on 19 November 1794. The winter of 1794–1795 was bitterly cold, reaching at one point. Because the roads were in poor condition, it took several weeks before provision convoys began reaching the
French camps with regularity. Arrangements were made to bake bread at
Grevenmacher and convoy it to the siege lines. Moreaux requested reinforcements in order to tighten the blockade and by 15 December the
Army before Luxembourg numbered 25,500 men. In addition, the
Army of Sambre-et-Meuse took over positions on the west bank of the Rhine that were formerly the responsibility of the
Army of the Moselle. French pickets were pushed to within of the Luxembourg defenses. The 12,000-man Luxembourg garrison was commanded by the octogenarian
Feldmarschall Johann von Bender. The fortress commandant was
Johann Wilhelm von Schröder and the brigade commanders were
Karl Philipp Sebottendorf, Johann von Moitelle and Ernst Beust. The garrison consisted of 10,095 infantry, 670 cavalry, 570 gunners, 88 sappers, 16 engineers and 415 volunteers. Altogether, there were nine Austrian infantry battalions, two battalions of Würzburgers and four squadrons of Austrian cavalry. On 9 January 1795, the garrison mounted a sortie by 3,000 picked volunteers in order to procure firewood from the surrounding villages. The blow fell on the French lines between
Merl and Fayencerie. At first the Austrians drove back the besiegers but they were thrown back into Luxembourg by French reinforcements and an artillery piece that Davout brought forward. In this skirmish, the French suffered 11 killed and 25 wounded while the Austrians lost 30 killed, a number of wounded and five cavalrymen taken prisoner.
MOREAUX is one of the
names inscribed under the Arc de Triomphe, on Column 13. At the end of March,
Jacques Maurice Hatry was ordered to undertake the siege with three fresh divisions from the
Army of Sambre-et-Meuse. In mid-April, the exchange of troops was carried out and the original three divisions were relieved. Bender surrendered the city on 7 June 1795. ==Notes==
