When the
Grande Armée left the shores of the
English Channel to fight in the
War of the Third Coalition, Rey was given command of the
Camp de Boulogne from 1805 to 1808. In the latter year he was named a
Baron of the Empire. He served as
chief of staff in
Laurent Gouvion Saint-Cyr's VII Corps in
Catalonia beginning in August 1808. It is probable that his brigade included three battalions each of the 12th Light and 43rd Line Infantry Regiments. At the
Battle of Baza on 4 November 1810, he led a brigade from
Horace Sebastiani de la Porta's 1st Division of the
IV Corps consisting of one battalion of the 32nd Line Infantry Regiment and three battalions of the 58th Line. He fought at the
Siege of Tarragona in 1811. Historian
David G. Chandler noted that Rey was appointed governor of the fortress of San Sebastián in August 1811. From 5 July to 9 September 1813 Rey conducted an extremely able defense of San Sebastián. In relating the story of the siege, Historian David Gates called Rey, "a commander of the first order." The army of the
Marquess of Wellington shipped 40 heavy siege cannon and large quantities of supplies to the nearby port of
Pasajes in early July. Wellington assigned
Thomas Graham, 1st Baron Lynedoch the British 5th Division and a Portuguese brigade to undertake the siege operation. An attempt to rush an outlying defense, the San Bartholomé Monastery, failed on 15 July. A heavier bombardment and attack pried the French defenders from the monastery two days later, but the Allied infantry gave chase and were bloodily repulsed with 200 casualties at the main defenses. The Anglo-Portuguese siege guns went to work and opened a small breach on the east side. Meanwhile, the British engineers discovered an old sewer which they utilized to place a mine under the southern defenses. The onset of the
Battle of the Pyrenees that day caused Wellington to order Graham to abandon the siege. As the Allies withdrew their siege guns, Rey launched a surprise sortie that inflicted 200 more casualties and seized some equipment. Shaken by their setbacks, Allied morale dropped and desertion became a problem. During the interlude, Rey repaired his southern defenses and thoroughly sealed off the breach with a new wall. He also shipped in fresh troops and supplies through the leaky British naval blockade and sent his sick and wounded soldiers back to France. Rey awaited a return of the Allies with 3,000 infantry and 60 cannon. The final assault began at 10:55 am on 31 August when
James Leith's 5th Division rushed the main breach from the south while Thomas Bradford's Portuguese brigade stormed the smaller one from the east. After running the gauntlet of mines and small-arms fire, both columns reached the tops of their respective breaches and came under murderous fire. After enduring the one-sided slaughter for nearly 30 minutes, both columns retreated to the base of the wall where the troops hugged the ground to escape the intense fire. In this emergency, Graham ordered his siege guns to fire over the heads of the surviving attackers. This expedient saved the day for the Allies, as the fire ripped apart the inner defenses, inflicting heavy losses on the French. As some of the 5th Division managed to make progress, an accident set off a store of bombs, killing 60 Frenchmen and injuring many more. Leith's men pushed along the walls toward the lesser breach where they assisted the Portuguese in breaking through. Still undefeated, Rey led his men in a house-to-house battle that finally ended when he and his remaining 1,300 troops took refuge in the La Mota Castle. Meanwhile, the Allied troops went berserk and sacked the city for three days in which the place was virtually destroyed. Ensconced in his hilltop castle, Rey held out against a 60-gun bombardment until 8 September when he finally ran up the white flag. Before being forced to surrender the survivors of his garrison, his soldiers inflicted over 5,000 casualties on their enemies, including Leith who was wounded. As a reward for his meritorious services, Emperor
Napoleon I of France promoted Rey to
general of division in November 1813 even though he was a prisoner of war. Historians differ when describing Rey's 1814 service.
David G. Chandler writes that he remained in British custody until May 1814. and
Toulouse in early 1814, but this was most likely his brother
Jean-Pierre-Antoine Rey. During the
Hundred Days Rey rallied to Napoleon and was given command of the fortress of
Valenciennes. After the restoration of the monarchy, he fell out of favor until 1830, when he received a three-year appointment to a royal commission. His military service is honored on Column 37 of the
Arc de Triomphe in
Paris, with the inscription
EEL REY. ==Notes==
