Waller was posted to the West Indies in 1807, arriving in time to witness the arrival of the last British slave ships "taking all possible advantage of the last weeks of their expiring commerce" (3). This journal describes his residence as a naval surgeon in Barbados, and his tour of duty in the Caribbean and South America during the Napoleonic wars. It depicts a contradictory and fast-changing colonial society, in which systemic racism, cruelty, and the "iron hand of slavery" (45) are beginning to be challenged. The journal includes a comparative view of slavery in the French and British colonies (89-97).
