[9] Fort Cachacrou was part of a line of signal stations organized by Captain Bruce, Royal Engineer, to get messages up and down the western coast.

[10][8] Using combinations of gun salutes and flag signals, a message could get from Fort Cachacrou to the garrison at Cabrits in less than half an hour.

[1][11][2] In anticipation of the invasion, French inhabitants of Dominica visited British troops at the fort on 6 September, getting them intoxicated and spiking the cannons with sand.

[12][13] Once the fort was captured, the French fired a celebration signal, which was the first notice of the invasion the British had in the capital of Roseau to the north.

Officer James Wallis received an official commendation for his conduct during the conflict while in charge of the outpost at Fort Cachacrou.
