Strategic Narrative Overview
Beginning on 4 September 1760, British land and naval forces encircled Pondicherry, cutting off French supply lines by both sea and land. The garrison under commander Lally found itself progressively starved of food, ammunition, and reinforcements. The blockade tightened through the autumn and winter months, leaving the French defenders with no viable means of resupply or relief. The garrison's position became untenable as stocks were exhausted.
01 / The Origins
The siege occurred within the wider context of the Seven Years' War, a global conflict pitting Britain against France across multiple theatres. In India, the two powers had long competed for colonial dominance through the Carnatic Wars. By 1760, British forces had gained the upper hand in southern India, and Pondicherry — the principal French colonial outpost on the Coromandel Coast — became the key remaining target for eliminating French influence in the region.
03 / The Outcome
On 15 January 1761, French commander Lally surrendered Pondicherry to the besieging British forces, having run critically low on supplies and ammunition. This was described as the third British victory in the region under Robert Clive's broader command. The fall of Pondicherry effectively extinguished organised French military power in India, leaving Britain as the dominant European colonial force on the subcontinent.
