The short version
- An 1847 letter reveals Sandbach, Tinne and Company received a ship carrying over three hundred enslaved people to Guyana, despite the British ban on the slave trade.
- The firm had previously received massive compensation from British taxpayers for the loss of enslaved laborers when slavery was formally abolished in 1833.
- These findings have spurred a new research initiative aimed at mapping the financial networks that sustained enslavement and its aftermath.
Recent historical analysis has brought to light evidence suggesting that a prominent British corporation continued the illegal trafficking of enslaved Africans to Guyana four decades after the formal abolition of the slave trade. The discovery centers on an 1847 letter written to the Liverpool office of Sandbach, Tinne and Company, which details the arrival of a vessel carrying hundreds of individuals described explicitly as cargo rather than passengers.
The correspondence was authored by Peter Miller Watson, who managed the company’s interests in Demerara, Guyana. He reported that the ship, named the Parker, arrived with 115 adult males, 86 adult females, 82 children under the age of fourteen, and 41 children under four years old. Watson noted only three deaths during the voyage, attributing these losses to the poor condition in which the individuals had lived on land before being shipped.
Malik Al Nasir, an author researching his family history, argues that the language used in the letter confirms the illegal nature of the transport. He points out that liberated Africans intercepted by the Royal Navy were not referred to as cargo, a term reserved for enslaved people treated as property. Furthermore, Watson’s attribution of deaths to the victims’ prior living conditions rather than the brutality of their former masters suggests these individuals were newly trafficked from Africa, likely evading naval blockades.
Sandbach, Tinne and Company was deeply embedded in the economic structures of the transatlantic slave trade. The firm, dominated by the Sandbach and Tinne families and their relatives in the Gladstone family, held substantial interests in the Demerara sugar industry. By 1847, the company had already received compensation payments from British taxpayers for the loss of enslaved people following the Slavery Abolition Act of 1833.
The financial scale of this compensation was significant. While John Gladstone, father of Prime Minister William Gladstone, received the largest individual payout, Sandbach, Tinne and Company secured the second-largest aggregate compensation. These payments were funded by British taxpayers, a debt that was not fully repaid until 2015. The firm continued to operate with these principal shareholders in place during the period the illegal trafficking occurred.
The persistence of such activities highlights the limitations of early abolition efforts. Although the Slave Trade Act of 1807 banned the trade in human beings and the Slavery Abolition Act of 1833 outlawed slavery itself, enforcement remained inconsistent. The Royal Navy’s West Africa Squadron intercepted fewer than ten percent of slaving ships, despite the loss of 1,600 sailors in the effort. Unregulated trading continued south of the equator, with traffickers sourcing people from regions such as Angola.
Even when the Royal Navy successfully intercepted vessels, the outcomes for those freed were often grim. Many so-called liberated Africans faced military conscription or were subjected to hard, unpaid labor under apprenticeship and indentured labor systems. These practices effectively perpetuated conditions of exploitation similar to slavery, undermining the spirit of abolition for many survivors.
The revelation of this letter has inspired a new research project titled Overwriting-Underwriting, which aims to uncover the financial networks behind enslavement. The initiative launches at the Museum of Liverpool on UNESCO’s International Day of Remembrance of the Slave Trade and its Abolition. It features contributions from academics and historians seeking to trace how wealth generated by slavery was maintained and expanded through subsequent economic mechanisms.
Peter Miller Watson, the author of the incriminating letter, was a distant cousin of William Gladstone and the father of Andrew Watson, who later became the first Black international footballer. This familial connection underscores the complex interplay between political power, commercial enterprise, and the legacy of slavery in British history. The findings challenge simplified narratives of abolition by revealing how entrenched interests continued to profit from human trafficking long after legal prohibitions were enacted.
As researchers delve deeper into these historical records, they aim to provide a more comprehensive understanding of the economic foundations of modern wealth. By examining insurance risk books and corporate correspondence, scholars hope to map the continuity between slavery-era profits and contemporary financial structures. This work seeks to address the enduring impacts of colonial exploitation on both former enslaved populations and their descendants.
