In 1799, Lake returned to England, and soon afterwards travelled to
British India where he was appointed
Commander-in-Chief. He took up his duties at
Calcutta in July 1801, and applied himself to the improvement of the
East India Company army, especially in the direction of making all arms, infantry, cavalry and artillery, more mobile and more manageable. In 1802 he was made a full general. On the outbreak the
Second Anglo-Maratha War in 1803 General Lake took the field against
Daulat Scindia, and within two months defeated the
Marathas at Kol (now called
Aligarh), after storming
Aligarh Fort during the
Battle of Ally Ghur (1 September 1803). He then took
Delhi (11September) and
Agra (10October), and won a victory at the
Battle of Laswari (1 November), where the power of Scindia was completely broken with the loss of 31 disciplined battalions, trained and officered by Frenchmen, and 426 pieces of ordnance. This defeat, followed a few days later by Major-General
Arthur Wellesley's victory at the
Battle of Argaon, compelled Scindia to come to terms, and a treaty was signed in December 1803. Operations continued against
Yashwantrao Holkar, who, on 17 November 1804, defeated Lake at the
Battle of Farrukhabad. Lake was now very frustrated by the
Jats and Yashwantrao Holker at
Bharatpur which held out against five assaults early in 1805. Cornwallis succeeded
Lord Wellesley as
Governor-General of India in July of that year – superseding Lake at the same time as commander-in-chief – and determined to put an end to the war. Cornwallis, however, died in October of the same year and Lake pursued Holkar into the
Punjab. However, after seeing the stronger position of Holkar and his effort to gather all Indian princes under one flag against the British, the British East India Company signed a peace treaty with Holkar which returned to him all his territory and promised no further interference from the Company. Lord Wellesley in a despatch attributed much of the success of the war to Lake's matchless energy, ability and valour. For his services, Lake received the thanks of
Parliament, and, in September 1804, was rewarded by being created Baron Lake of
Delhi and Laswary and of Aston Clinton in the
County of
Buckingham. From 1801 to 1805 Lake was
Commander-in-Chief, India, then again from 1805 to 1807 as his successor
John Graves Simcoe had died before heading off to India. At the conclusion of the war he returned to England, and in 1807 he was created
Viscount Lake of Delhi and Laswary and of Aston Clinton in the County of Buckingham. One of his sons Major
George Augustus Frederick Lake accompanied him in Ireland and then India, acting as his aide-de-camp and military secretary during the campaign: at one stage offering his mount when the elder Lake's horse had been shot from under him at an engagement near the village of Mohaulpoor. Minutes after seeing his father mounted Major Lake was seriously wounded in the presence of his father. Lake recovered from his wound and went on to command the 29th Regiment of Foot during the Peninsular Campaign. He was killed in action at the
Battle of Roliça, Portugal on 17 August 1808. == Parliamentary career ==
