in Lille, in preparation for the planned invasion of England; he remained there until the idea was abandoned. In August 1805, Gazan commanded of a division of the army that encircled Austrians in Ulm. On November 11, under Marshal Mortier, his division provided the advance guard in the march against Kutuzov's army. As they advanced through a narrow Danube canyon, the division was isolated from the main force, near Dürenstein. By the small village on the Danube, famous as the prison of Richard the Lionhearted at the end of the twelfth century, he and his division were trapped in a narrow canyon, attacked by a Russian force at his rear and more Russians at his front. Gazan's division fought desperately for a harrowing day and suffered 40 percent casualties. He and Mortier were finally rescued by the arrival of the VIII. Corps' 1st Division, commanded by Pierre Dupont de l'Étang, but only after the loss of nearly 4,000 men. In addition, 47 officers and 895 men were captured, and he lost five guns, as well as the eagles of the 4th Infantry Regiment, and the eagle and guidon of the 4th Dragoons. As recognition of his conduct in "the immortal Battle of Dürenstein", he received the Officers Grand Cross of the Legion of Honor and the survivors of his division was sent to Vienna to recuperate. When Austria sued for peace, Gazan's division was sent to Würzburg in Bavaria, where it remained until Prussia declared war in October 1806. Gazan's division fought in the French victory over Prussia at the Battle of Jena-Auerstedt (14 October 1806). At Ostrolenka (16 February 1807), Gazan's troops took three guns and two Russian colors. Otherwise, his troops stayed in their winter quarters. After the new peace treaty, Gazan's troops were sent to Silesia to restore order. In 1808, he was named Comte de la Peyriére. Early Peninsular War In October 1808, now attached to the VI. Corps, Gazan went to Spain with Jean Lannes and arrived at Zaragoza in December. The city was under siege and defended by Spanish under José de Palafox. Lannes ordered an attack on 22 January 1809 to capture the city in street by street fighting; when the French took a block, sappers tunneled under the houses and blew them up, which prevented Spanish street fighters from slipping into houses behind them. The method was effective but painstaking. Gazan's assignment,
