The scene

Canton, 1839: the order

Canton, spring 1839. The emperor’s commissioner, Lin Zexu, gives the foreign merchants one order: hand over your opium. Within weeks some 20,000 chests are in Chinese hands. What happens to them, and how Britain and China come to war within months, is this lesson’s question.

Was this a war about a drug, or about something larger? The answer depends on which sources you trust.

The place

Canton

Canton, today Guangzhou in southern China, was the port where foreign merchants traded with China. Their ships brought goods in, and the trade in opium grew in the same port.

What is new in 1839 is a commissioner with the power to carry out the emperor’s decision to stop it.

The question is simple to ask and hard to answer: how did a trade in one drug lead to war?

The emperor’s commissioner at Canton in 1839, who took the merchants’ opium and wrote to Queen Victoria.

  • Born: 1785
  • Died: 1850
  • Won: The surrender of about 20,000 chests of opium, 1839
  • Lost: War with Britain, 1839–1842

The drug harms the people, and the trade must end.

The road to it

Background

A ban decided in the capital

In 1836 an official sent the emperor a memorial with a different idea: let the trade be legal, and tax it. Two years later another memorial argued for a total ban, and in 1838 the emperor approved the ban.

Daoguang had reigned since 1820. At the end of 1838 he named Lin Zexu imperial commissioner and sent him south, to Canton, to end the trade.

Note the order. The ban was decided in the capital, before Lin had seen Canton. Historians still argue about what the court really thought, and we will come back to that.

1839

The foreign merchants

Lin reached Canton in 1839, though accounts differ on when. He dealt with Britain’s superintendent, Charles Elliot, and with the merchants who held the opium.

Lin wanted the stock handed over, and the opium stayed in the merchants’ hands while the pressure grew.

According to one account, Lin’s rules made foreign traders liable to execution. For anyone holding opium, that was a frightening rule.

A decision point

You are Charles Elliot, Britain’s chief superintendent of trade in China.

Late March 1839, Canton.

The British merchants hold a large stock of opium. Lin has demanded it, and the merchants are waiting for your decision.

You have heard that Lin’s rules make foreign traders liable to execution. You have also heard that the merchants fear losing their money if they hand their stock over for nothing.

You do not know whether London will pay for the opium.

What do you do?

  • Order the merchants to hand over their opium, and promise that the government will pay for it. Probably the chests come in and the trade stops for now. But the promise would be yours alone, and London might refuse to honour it.
  • Refuse, and let the merchants keep their chests until London decides. Probably Lin would press harder. According to one account, his rules made foreign traders liable to execution, so the merchants would be in danger.
  • Ask Lin for more time, and wait for London’s answer before giving any order. Probably Lin would grant a short delay. But delay would not end the trade, and the stand-off would only grow.

What really happened

Order the merchants to hand over their opium, and promise that the government will pay for it.

Elliot set the deadline and ordered the merchants to surrender their opium, and he also asked Lin for more time. Owners said he had promised them compensation from the British government. The sources disagree on what he promised, and on whether he had the authority to promise it.

Elliot was responsible for the British in Canton, and he could not know whether London would pay. Historians still argue over how far his promise went.

The chests

Spring 1839

The surrender

about 20,000 chests

According to most accounts, the surrender went on through April and May 1839. The total is about 20,000 chests, a figure that comes mostly from Lin’s own letter.

The exact number is disputed. Later books give slightly different totals, so remember it as about 20,000.

Now the chests are in Chinese hands, and the question is what to do with them.

The argument

Why the drug is the problem

Lin’s letter makes two arguments. The first is moral: the drug harms the people who use it. The second is economic: the trade drains wealth out of China.

We will read the letter itself in chapter four, because its date is uncertain.

Keep these two arguments in mind. They help explain the choice in front of him.

A decision point

You are Lin Zexu, the emperor’s commissioner at Canton.

May 1839, Canton.

The merchants’ opium is now in your hands: about 20,000 chests. The emperor wants the trade ended, and that is why you were sent.

You believe the drug harms people, and that the trade drains wealth out of China.

There are two ways to be rid of the chests. Each has its risks.

What do you do with the opium?

  • Destroy it on the shore at Humen, and let the river carry the remains out to sea. Probably the chests are gone for good, and the ban looks serious. But the merchants lose their stock, and London may treat the act as a reason for war.
  • Sell the opium through local buyers, and put all the money into the state’s treasury. Probably the money goes to the state, but the drug keeps its market. The ban would then look like a trade, and the harm would go on.

What really happened

Destroy it on the shore at Humen, and let the river carry the remains out to sea.

Lin chose to destroy it. The work began at Humen on 3 June 1839.

His letter argues that the drug harms people, so destruction fitted his case. No source we know of shows him weighing a sale. The second choice is offered for analysis, not as something he considered.

3 June 1839

Into the sea

about 23 days

On 3 June 1839 the destruction began at Humen, on the river not far from Canton. According to most accounts, workers mixed the opium with salt and lime and washed it out to sea.

The work took about 23 days. For the foreign merchants it meant the loss of their stock. For Britain, the loss became a reason to fight. Historians call such a reason a casus belli.

What we really know

Source: Lin’s letter to the Queen

Paraphrase, not a quotation. Lin asks the Queen to stop her subjects trading in opium. He says the drug harms people, and that the trade drains China’s wealth.

Paraphrase of Lin Zexu’s letter to Queen Victoria, dated only “1839”.

The letter has no date beyond the year. Some sources suggest it was lost on the way, and historians still debate whether the Queen ever read it.

  • Who wrote it, and to whom? An imperial commissioner, writing to a foreign queen. It is a diplomatic appeal: Lin asks her to act.
  • When was it written? Only the year 1839 is known. It was written weeks or months after the merchants handed over their opium, but the day is not known.
  • What is missing? Any answer from the Queen, and any proof that the letter reached her. We hear only one side: that of the official who seized the stock.

Myth

Britain fought the Opium War for free trade.

The truth

Only partly, and historians disagree on how much. Stephen Platt, in his 2018 book, presents the British push to open trade as the start of the collapse of the Qing dynasty, China’s ruling house, and reviews of the book are divided. Others put the drug at the centre of the story. The version that Britain forced opium on China is also only partly true.

The evidence

Article IV of the 1842 treaty makes China pay for the opium surrendered in 1839. The articles say nothing about the trade itself.

“the Island of Hong-Kong, to be possessed in perpetuity by Her Britannic Majesty”

Treaty of Nanking, Article III, 29 August 1842 (English text, as printed on Wikisource).

The treaty was signed at Nanking, aboard the British warship HMS Cornwallis. It was written at the end of the war, by the winning side, under naval pressure.

  • Who wrote it, and who held the upper hand? British and Qing negotiators drafted it, but at the end of a war that Britain had won at sea. The text was shaped under naval pressure.
  • What does the article say the island is for? It says the island is to be held “in perpetuity”, that is, for ever. It does not say why Britain wanted it.
  • What is left out? Kowloon, on the mainland opposite the island, is not in this article. The article also says nothing about the opium trade.

A decision point

You are William Ewart Gladstone, Member of Parliament for Newark.

8 April 1840, the House of Commons in London. Two years before the treaty.

The Commons is debating the war with China. A motion against the government’s handling of it is before the House, moved by Sir James Graham.

You know the facts of the seizure at Canton. Some say the merchants were promised compensation. Others say the superintendent had no authority to end the trade at all.

Other members will speak from the other side. Your words will be recorded in the official report of Parliament.

Do you rise to speak, and what do you say?

  • Speak in the debate against the war, and give your reasons. Probably the government’s friends answer you sharply, and both sides quote your words. But the House hears a clear case against the war.
  • Speak in the debate in defence of the government’s conduct, and give your reasons. Probably the government’s supporters welcome you, and the motion looks weaker. But you would be defending a war whose causes historians still dispute.
  • Stay silent, keep your views to yourself, and let the debate go on without you. Probably your name does not appear in the debate, and nobody can say where you stood. But the motion is decided without your voice.

What really happened

Speak in the debate against the war, and give your reasons.

Gladstone spoke against the war, saying it was unjust in its origin (col. 818). The House held a division on 9 April: 262 for the motion and 271 against.

The record shows his argument, not his private reasons. Others took the other side: Lushington argued that the superintendent had no authority to end the trade, and Sandon called the attacks on Gladstone unjust.

What followed, and the quiz

1842

The price of the peace

21 million dollars

On 29 August 1842 the treaty was signed at Nanking, aboard a British warship. China agreed to cede the island of Hong Kong, and to open five treaty ports, among them Shanghai, to British trade.

China also agreed to pay an indemnity of 21 million dollars. The first payment, 6 million dollars, was due at once. The rest was due in instalments until the end of 1845.

For Britain, the result was an island and five new ports. For China, it was a large bill and the loss of an island. Historians still argue about what the war was for, and about what the treaty really meant.

What followed, in order

  • End of 1838 The emperor names Lin Zexu imperial commissioner at Canton.
  • 3 June 1839 Destruction of the opium at Humen begins. It lasts about 23 days.
  • 4 September 1839 A naval clash at Kowloon.
  • 9 April 1840 The Commons debates the war. A motion against the government is defeated by a majority of nine, 262 to 271.
  • 7 January 1841 British naval and army forces take two forts at the mouth of the Pearl River.
  • 29 August 1842 The Treaty of Nanking is signed aboard HMS Cornwallis.
  • 26 June 1843 The two governments exchange ratifications at Hong Kong.

Why did the war happen?

What was the war really about: the drug, the trade, or the politics of the Qing court?

  • Stephen R. Platt, 2018 British efforts to open trade, he argues, set off the collapse of the Qing. Several causes lay behind that collapse: rebellion, the Canton trading system, and a split at court over whether to legalise opium or drive out the foreigners. Reviews of his book disagree about how much weight he gives each cause.
  • Julia Lovell, 2011 Her book of 2011 is titled for the drug and the dreams around it, and its title alone places the opium trade at the centre of the story. Read the book for the full argument.
  • James Polachek, 1992 His book, The Inner Opium War, looks at the fight inside the Qing court. According to a review, Lin’s supporters pushed for hard resistance for reasons of domestic politics.
