Siddharth Kara's The Zorg: A Review of Almost Unthinkable Horrors at Sea

Over the spanning nearly four centuries, the transatlantic slave trade resulted in 12.5 million Africans trafficked from their homelands to the Americas. A devastating 1.8 million of those souls perished during the Middle Passage, subjected to scarcely imaginable conditions of overcrowding, squalor, and illness. Some took their own lives by throwing themselves overboard, whereas others were callously thrown into the sea.

Two Interwoven Narratives

In The Zorg, author Siddharth Kara presents two parallel narratives. The first details a horrific incident aboard the namesake slave ship—the systematic drowning of 132 enslaved Africans by its British crew. The second story explores how this event came to influence the ending of the Atlantic slave trade in 1807, driven in large part by the dedicated work of a dazzling array of abolitionist activists. Among them was Olaudah Equiano, who authored one of the rare first-person narratives of the Middle Passage, describing it as “a scene of horror almost inconceivable”.

Liverpool's Central Role

The tale originates in Liverpool, a port city that at the peak of its economic power was responsible for 40% of Europe's slave trafficking. Investing in slavery was a highly profitable venture for everyone from the elites to the working classes. One such entrepreneur, William Gregson, accumulated his earnings from rope-making, invested them into the slave trade, and rose to become a prominent citizen and even mayor. Gregson financed the slave ship The William, which set sail from Liverpool for West Africa in October 1780 under Captain Richard Hanley. Its cargo was loaded with commodities like tobacco, firearms, knives, and so-called “India goods” such as chintz and cowrie shells—the latter being a standard rate in the purchase of human beings.

A Ship Seized

Around the same time, a Dutch slave vessel named the Zorg (later anglicized by the British as the Zong) had departed the Netherlands. With Britain declaring war on the Dutch in late 1780, the Royal Navy gave British ships authority to seize Dutch property at sea—a de facto license for privateering. The Zorg was subsequently taken by a British captain and held off the Gold Coast. Meanwhile, Captain Hanley, during one of his voyages, picked up a fleeing British governor named Robert Stubbs, who had been expelled for graft.

The Nightmare Passage

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

Kara is particularly skilled at using contemporaneous sources to bring to life the general hell of being transported on a slave ship.

The Zorg's journey was fraught with calamity. "The flux" swept through the vessel, followed by scurvy. The captain succumbed to sickness, lost his senses, and handed command over to Stubbs. Thus, “a ship full of decay and death was being commanded by a passenger.” Kara masterfully utilizes period testimonies to paint a picture of the sheer horror. The powerful testimony of Alexander Falconbridge, a ship's surgeon turned abolitionist, describes how the enslaved people's skin was frequently worn down to the bone from lying on bare wood, their flesh caught between the planks.

The Unspeakable Decision

By late November 1781, the Zorg was still miles from Jamaica and critically short on water. The crew resolved to jettison 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 pleaded to be allowed to live, even without water rations—but by pure economic greed. Maritime insurance policies did not cover losses from natural causes, but they did cover cargo discarded out of “necessity” for the ship's safety. Over a period of days, the crew murdered “those Africans who would be worth less at auction”—the infirm, the sick, including women and children, among them a baby born during the voyage.

Insurance and Injustice

Back in Liverpool, investor William Gregson was dissatisfied with the profit on his investment. He submitted an insurance claim for £30 per lost slave—a substantial sum in today's money. The insurers refused to pay. In March 1783, Gregson took them to court and won a trial by jury, with his lawyers claiming that throwing the enslaved people overboard had been “necessary.”

Catalyzing the Movement

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.” Just twelve days after the trial, an anonymous letter appeared in a widely read English newspaper. The author, who claimed to have been present the court proceedings, argued compellingly against slavery, using the Zorg case as a prime example of its brutality. Olaudah Equiano saw the letter and brought it to the activist Granville Sharp, who filed a motion for a new trial. At the subsequent hearing, the events on the Zorg were reviewed in meticulous detail, exactly what the abolitionists had hoped for.

A Sustained Campaign

In the spring of 1787, the founding members of the Society for Effecting the Abolition of the Slave Trade convened. Over the subsequent years, they wrote letters, orated, lobbied tirelessly, 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 struggles, the Act for the Abolition of the Slave Trade was finally passed in 1807.

An Enduring Impact

The debate over who or what should be credited for abolition is contentious. The Zorg's legacy, 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 prolonged public movement was historic, serving as an affirmation to the power of moral courage, the pen, and relentless persistence.

Kara's Narrative Method

In contrast to his previous books—such as the acclaimed Cobalt Red—Kara has had to address certain lacunae in the historical record. At times, speculative passages sit awkwardly next to scrupulously factual accounts, giving the book a somewhat hybrid feel. A blend of narrative suspense and part historical analysis, The Zorg ultimately manages to illuminating one of history's most horrific episodes, using compelling prose and documented fact to assemble a account that haunts the reader long after the final page.
