British Army Major General. The son of Robert Alexander Lambert, a captain in the Royal Navy. In 1791, he was commissioned as an ensign in the 1st Foot Guards, and served in France, Ireland, the Netherlands, Portugal and Spain, including the incident at Corunna in which Sir John Moore lost his life. In 1813, he was promoted to the rank of Major General and commanded the 6th Division at the battles of the Nivelle, the Nire, Orthez and Toulouse. He received the thanks of Parliament and was made a Knight Commander of the Bath. He was then sent to America and, on January 6, 1815, joined the Army under Sir Edward Pakenham, near New Orleans. Two days later, in the unsuccessful attempt on the American trenches, Pakenham and Sir Samuel Gibbs were both killed, and Lambert took over the chief command. He decided not to renew the attack and, on January 18, retreated. He and a force of 1,400 proceeded to Fort Bowyer, on the Bay of Mobile in Alabama. They approached to within 200 yards of the wooden fort and began to build their siege works, during which they endured constant fire from the Americans and suffered a few casualties. By February 12, the siege guns were in place and the British launched a small barrage of artillery. Lambert then visited the American commander, Major William Lawrence, under a flag of truce, and asked him to capitulate. Lawrence realized that any further resistance would result in the needless slaughter of the troops under his command, and agreed to accept the British terms of surrender. The following day, a British dispatch ship arrived with the news that, on December 24 of the previous year, the Treaty of Ghent had been signed and had brought an end to the War of 1812. Lambert then returned to Europe to command the 10th Brigade of Infantry at the Battle of Waterloo. The Brigade arrived from Ghent only on the morning of the battle (June 18). At first, it was posted in reserve at Mont St. Jean, but, after three o'clock in the afternoon, it was moved up to support the 5th Division under Thomas Picton, who was killed in action. The 27th Regiment of the 5th brigade lost two-thirds of its men, this being a heavier loss than that of any other regiment. Lambert once more received the thanks of Parliament, as well as the Order of St. Vladimir of Russia and the Order of Maximilian Joseph of Bavaria. During the occupation of France, he commanded the 8th Infantry Brigade. In 1816, he married Jane Morant; was promoted to Lieutenant-General in 1825; made a Knight Grand Cross of the Bath in 1838; and was promoted to General in 1841. He died at Weston House, in Thames Ditton in Surrey.
