the battle, the Russians were able to retreat in good order and the eagle was not recovered, much to the emperor's regret. In 1807, at Heilsberg, the was overthrown by Prussian cavalry and Russian infantry. An eagle was lost and several officers, including a colonel, were killed. The eagle was captured by NCO Anton Antonov of the Pernov Musketeers. Prussian historians dispute this, claiming that the Prittwitz Hussars captured the eagle. In 1807, near Eylau, the lost its flag and eagle to the Russian . In 1812 at Krasnoi, the 18th Régiment d'Infanterie de Ligne again lost its eagle and was "virtually destroyed" by the Russian . In 1808, at the Battle of Bailén, the French corps led by General Dupont surrendered after being defeated by a Spanish army led by generals Castaños and Reding; this was the first surrender of an Imperial field army. As part of the capitulation terms, the French gave up their flags and banners, including three eagles. These eagles were kept in the Cathedral of Seville until they were recovered by the French in 1810 and sent back to Paris. The first French eagles to be captured by the British were taken by during the Invasion of Martinique including the Eagle of the 82nd French Regiment of the Line. Subsequently the 87th Regiment of Foot took an Imperial Eagle at the Battle of Barrosa on 5 March 1811. At Barrosa, Ensign Edward Keogh and Sergeant Patrick Masterson captured the French Imperial Eagle of the . Keogh only managed to get a hand on the shaft when he was shot, bayoneted and killed. Masterson took over and, after killing several men, wrenched the Eagle from the dying hands of its bearer, Lieutenant Gazan. The eagle was taken back to the United Kingdom and put on display in the Royal Hospital Chelsea. It was around 10 inches tall, set on a plinth marked with the numeral 8. It was made of silver, but gilded, which led many to think it was solid gold. In fact, the only golden part of the eagle was a laurel wreath which hung around its neck. This wreath was an honour conferred upon the 8th Regiment by Napoleon himself, and was not common to all eagles at the time. The gold leaves were presented to a number of regiments that were present at the Battle of Austerlitz by the city of Paris.
