. Such a portrait formerly hung in the Banqueting Hall of Government House, Madras He seems to have entered the army in 1727 and served in
Gibraltar and
Flanders, subsequently taking part in the
Battle of Culloden. In 1748, with the rank of
major and the reputation of an experienced soldier, he went out to
India to command the
East India Company's troops.
Dupleix's schemes for the French conquest of southern India were on the point of taking effect, and not long after his arrival at
Fort St David, Lawrence was actively engaged. He successfully foiled an attempted surprise by French troops at
Cuddalore, but was captured by a French cavalry patrol at
Ariancopang (modern
Ariankuppam) whilst leading forces to assist Admiral
Edward Boscawen in enforcing the
Siege of Pondicherry in 1748. He was kept prisoner by the French until the
peace of Aix-la-Chapelle. In 1749 he was in command at the capture of
Devicota, during which one of his subordinate officers was
Robert Clive (1725–1774), the future
Commander-in-Chief of British India, with whom a lifelong friendship began. When Clive had become famous he honoured Lawrence by refusing to accept a sword of honour unless one was voted to him also, as the creator of the Indian army. In 1750 Lawrence returned to England, but he was back in India by 1752. Here he found Clive in command of a force intended for the relief of
Trichinopoly. As senior officer Lawrence took over the command, but was careful to allow Clive every credit for his share in the subsequent operations, which included the relief of Trichinopoly and the surrender of the entire French besieging force. In 1752 with an inferior force he defeated the French at
Bahour and in 1753 again relieved Trichinopoly. For the next seventeen months he fought a series of actions in defence of that place, and finally arranged an armistice of three months, afterwards converted into a conditional treaty. He was commander-in-chief until the arrival of the first detachment of regular forces of the crown. In 1757 he served in the operations against
Wandiwash, and in 1758-1759 was in command of
Fort St George, Madras, during the siege by the French under
Lally. In 1759 failing health compelled him to return to England, but in 1761 he resumed his command as
major-general and commander-in-chief. Clive supplemented his old friend's limited income by settling on him an annuity of £500 a year. In 1765 he presided over the board charged with arranging the reorganisation of the Madras army, and he finally retired the following year. ==Retirement, death and succession==
