Napoleonic Wars Lieutenant General George de Grey, 3rd Baron Walsingham (11 June 1776 – 26 April 1831) was a British peer and Army officer.
In early 1796 de Grey's regiment was sent to serve in India, as part of which journey they witnessed the Capitulation of Saldanha Bay in August 1796 off Cape Colony.
The regiment was garrisoned in Kent and de Grey stayed there with them for the following two years, until in 1803 he was appointed an assistant adjutant general for the Home District.
[3][4] He fought in command of his brigade at the subsequent Battle of Bussaco on 27 September and then formed part of the rearguard of the army as it retreated to the Lines of Torres Vedras for the winter.
[3] With the threat of an attack by the French now lessening, de Grey's brigade was sent to join Marshal William Beresford's force marching to fight at the Siege of Badajoz.
Then at the Battle of Usagre on 25 May de Grey's force saw its greatest success, destroying a brigade of French dragoons in a fight that saw 250 Frenchmen killed to only 20 British soldiers.
[3] In the middle of 1811 de Grey injured his shoulder and requested to Lord Wellington, the commander of the army, that he be allowed to return home to recuperate.
At some point after his brigade had moved to Ciudad Rodrigo de Grey was given permission to leave his command, and by the end of the year he had done so, although the exact date of his departure is unknown.
