The Zorg by Siddharth Kara: An Examination of Scarcely Imaginable Horrors at Sea

Over the course of nearly four hundred years, the transatlantic slave trade resulted in 12.5 million Africans forcibly taken from their continent to the Americas. A devastating 1.8 million of those individuals perished during the voyage, enduring unfathomable conditions of extreme confinement, filth, and disease. Many chose to end their suffering by throwing themselves overboard, whereas others were callously thrown into the sea.

A Tale of Two Stories

In The Zorg, author Siddharth Kara weaves together two interconnected narratives. The first details a horrific incident aboard the eponymous slave ship—the systematic drowning of 132 captive individuals by its British crew. The second story explores how this event came to influence the abolition of the Atlantic slave trade in 1807, thanks largely by the dedicated work of a dazzling array of abolitionist activists. Among them was Olaudah Equiano, who wrote one of the rare first-person narratives of the Middle Passage, calling it “a scene of horror almost inconceivable”.

Liverpool's Central Role

The tale begins in Liverpool, a port city that at the height of its economic power was responsible for 40% of Europe's slave trade. Financing slavery was a lucrative venture for everyone from the elites to the common people. One such investor, William Gregson, accumulated his wages from his trade, ploughed them into the slave trade, and rose to become a prominent citizen and even mayor. Gregson provided the funds for the slave ship The William, which set sail from Liverpool for West Africa in October 1780 under Captain Richard Hanley. Its cargo was filled with trade goods like tobacco, firearms, knives, and so-called “India goods” such as chintz and cowrie shells—the latter being a standard rate in the acquisition of human beings.

A Ship Seized

Around the same time, a Dutch slave vessel named the Zorg (later referred to by the British as the Zong) had departed the Netherlands. With Britain at war with the Dutch in late 1780, the Royal Navy granted British ships permission to seize Dutch ships at sea—a virtual sanctioning of piracy. The Zorg was soon taken by a British captain and anchored off the Gold Coast. Meanwhile, Captain Hanley, on a slaving expedition, took aboard a disgraced British governor named Robert Stubbs, who had been removed for corruption.

The Nightmare Passage

When Hanley arrived at Cape Coast Castle—a stronghold with a notorious holding cell beneath it—he assumed control of the captured Zorg. He proceeded to grossly overload it with captives, put a dozen of his own crew on board, and appointed Luke Collingwood, a ship's surgeon of dubious seamanship, its captain. In August 1781, the Zorg left Accra carrying 442 captives, 17 crew members, and one depraved passenger: the former governor, Robert Stubbs.

Kara excels in using historical documents to bring to life the general hell of being transported on a slave ship.

The Zorg's journey was plagued with disaster. "The flux" ravaged the vessel, and then scurvy. The captain fell ill, became delirious, and handed command over to Stubbs. Thus, “a ship full of decay and death was being commanded by a passenger.” Kara effectively employs period testimonies to illustrate of the sheer horror. The graphic testimony of Alexander Falconbridge, a ship's surgeon turned abolitionist, details how the enslaved people's skin was often rubbed raw to the bone from being packed on bare wood, their flesh caught between the planks.

A Calculated Atrocity

By late November 1781, the Zorg was still far from Jamaica and dangerously short on water. The crew resolved to throw overboard a number of the enslaved Africans, who had already endured months of appalling conditions below deck. This unspeakable act was not motivated by ensuring survival—the Africans had begged to be spared, even without water rations—but by pure economic greed. Ship insurance policies did not cover losses from disease, but they would pay for cargo jettisoned out of “necessity” for the ship's safety. Over a period of days, the crew drowned “those Africans who would be worth less at auction”—the infirm, the sick, including women and children, even a baby born during the voyage.

The Courtroom Battle

Back in Liverpool, investor William Gregson was dissatisfied with the financial return on his venture. He submitted an insurance claim for £30 per drowned captive—a substantial sum in today's money. The insurers declined to pay. In March 1783, Gregson took them to court and was awarded a trial by jury, with his lawyers arguing that throwing the enslaved people overboard had been “necessary.”

The Spark for Abolition

According to Kara, “there is a direct line of causality between the public exposure of the Zorg murders and the first movement to abolish slavery in England.” Merely twelve days after the trial, an published essay appeared in a prominent English newspaper. The author, who claimed to have been present the court proceedings, made a powerful case against slavery, citing the Zorg case as a key illustration of its brutality. Olaudah Equiano read the letter and brought it to the abolitionist Granville Sharp, who filed a motion for a new trial. At the following hearing, the events on the Zorg were reviewed in forensic detail, precisely what the abolitionists had wanted.

The Road to 1807

In the spring of 1787, the founding members of the Society for Effecting the Abolition of the Slave Trade convened. Over the following years, they wrote letters, orated, organized campaigns, and gathered evidence on the particulars of the slave trade. “Their efforts,” Kara writes, “would lay a blueprint for the pursuit of social justice.” After years of setbacks, the Act for the Abolition of the Slave Trade was finally passed in 1807.

An Enduring Impact

The question of who or what should be credited for abolition remains a matter of debate. The Zorg's influence, however, is visibly captured by J.M.W. Turner's famous painting, The Slave Ship, which was based on the events of 1781. While slavery has been widespread in human history, its abolition following a sustained public movement was historic, serving as an testament to the power of moral courage, the pen, and relentless determination.

The Author's Approach

In contrast to his previous books—such as the Pulitzer finalist Cobalt Red—Kara has had to fill in certain gaps in the historical record. At times, imaginative flourishes contrast with scrupulously factual accounts, giving the book a somewhat chimeric feel. A blend of narrative suspense and part historical analysis, The Zorg ultimately manages to shedding light on one of history's most horrific episodes, using compelling prose and meticulous research to assemble a account that haunts the reader long after the final page.
