Saltwater Slavery: Key Concepts (Notes)

The transformation of African captives into Atlantic commodities begins at the littoral, where land meets sea and captives are converted into marketable cargo.
At the shore, captives move from being people to being exchangeable assets: they are enclosed in coastal forts or aboard ships that function as floating warehouses.
The coastal border is where violence, social abstraction, and economic logic converge to render captives as commodities, a process sustained by a broader system of market violence.

English trading posts (Cape Coast Castle, Accra, Anomabu, etc.) housed captives in purpose-built spaces (dungeons, bastions, and rock-cut prisons).
Captives were categorized in shop/ship language as either "shipping slaves" or "castle slaves" (often called Arda slaves at the castle); facilities varied but all served to imprison, inventory, and prepare captives for export.
Prisons could hold captives for days to months; overcrowding and poor building conditions were common, with walls, ventilation shafts, and even underground cells designed to deter insurrection.

Shackles (short irons for wrists; long irons for ankles) were essential but often in short supply; some ships and forts operated without regular iron supply.
Security depended on a mix of physical confinement (prison walls, damp spaces) and social control (keepers, bumboys, and guard practices).
Escape attempts were frequent: prisoners dug walls, exploited weak foundations, and escaped during work details; coastal sites were porous, enabling some to reach the water and swim for freedom.

Rations were calculated to balance cost with life support, not to sustain health: roughly $\tfrac{1}{10}$ to $\tfrac{1}{5}$ of a bushel of corn per person per day.
A single chest of corn could feed a large group for a period; rations varied with stock and market conditions, often becoming scarce as slave populations grew.
Can key local foods and preparation: corn ground on local stones (cankey), mixed with water and palm oil to form dense bread-like porridge; women often prepared the meal according to local custom.
Seasonal and market fluctuations could leave captives undernourished, sometimes leading to illness and death; provisioning was driven by economic prudence rather than humanitarian concern.

Traders described captives with terms like "lusty" and "likely" to mask weakness and to project market-friendly images of vitality.
The market created a logic in which a human body could be treated as priceable capital, and buyers could justify removal from social life as a legitimate business transaction.
The phrase "slaves in chaines" and other descriptors reflected a system that sought to erase social identity in favor of exchange value.

Captives entered a state of social death: marginalized, estranged from kin, and legally inseparable from market ownership.
Redemption or rescue occurred only rarely and often came at the expense of others; most captives remained tied to the Atlantic market and were vulnerable to recapture or resale.
Enslavement severed ties to kin and community; in some African societies, the social death of the slave was conceptualized as a liminal state between life and ancestorhood, with the possibility (in theory) of ritual reintegration or, more commonly, perpetual marginality.

Escape attempts increased as captives faced starvation, overcrowding, and brutal conditions; many ran from prisons or ships and tried to reach kin communities or shoreside refuges.
Local elites (cabosheers) could recapture runaways for a price, sometimes demanding goods (e.g., cloth or other valuables) before handing the captive back to Europeans.
Even when runaways returned to Africa, their fate often remained tied to the market; recaptured runaways were frequently resold, sometimes back to different buyers.
The market’s logic meant escape did not guarantee freedom or return to community; the price of recapture and resale often outweighed any potential social reintegration.

The Atlantic market produced a pervasive social death by converting people into sellable objects and by reframing loss as economic opportunity.
The phrase that a human could be treated as if not a person under market pressure reflects a systemic belief in exchangeable value over social belonging.
The littoral and slave ships together constituted a single, powerful apparatus: capture, confinement, dehumanization, and sale that bypassed kinship and community ties.
The running implication is that the market, as a logic and institution, created a form of social death for the saltwater slave that was nearly irreversible for most individuals.

Littoral as frontier of commodification; coastal forts and ships as factories of sale.
Slaves in chaines vs Arda/castle slaves; dungeon architecture as security and control.
CanKEY bread and ration arithmetic: $\tfrac{1}{10} \le \text{ration} \le \tfrac{1}{5}$ bushel per person per day; canney as ground corn.
Language of commerce:
- "lusty" and "likely" as market-desired descriptions; desexualized vitality masking decline.
- "shipping slaves" vs "castle slaves" distinctions as a way to manage inventory and truth-telling.
Social death and liminality: slaves as socially dead, never fully integrated; ritual and ancestor concepts used to explain or justify separations.
Escape, redemption, and recapture: cabosheers, prices in exchange for return; frequent double sale of runaways.
The market as technology of power: the alchemy of turning humans into currency; integration of language, law, and logistics to sustain commodification.
