After the surrender of Dominica to a British expeditionary force, the French in Martinique fully expected the same expedition to head into their direction.
Two days later the British amphibious force anchored in Sainte-Anne Bay, just round the southern extremity of Martinique, on the western side.
On 16 January, the entire British army was landed without loss of a man at Case Navire, a little to the north of Negro Point.
This point forms the northern headland of the harbour, and had at its foot a road leading due east over the mountains to Fort Royal, some 5 kilometres (3.1 mi) away.
The way was blocked by deep gullies and ravines, and the French had erected redoubts at every strategic point, as well as batteries on a hill beyond, named Morne Tortenson.
The pursuers plunged down into the intervening ravine after the French and swarming up Morne Grenier "by every path, road, and passage where men could run, walk, or creep," hunted the fugitives headlong before them.
Monckton had already made arrangements for the capture of Tobago when he received orders requiring the presence of his troops for the attack on Havana, Cuba.
