(Redirected from Shimonoseki Expedition, Japan)
The 'Bombardment of Shimonoseki' (Japanese:下関戦争/馬関戦争, ''Shimonoseki SensÅ/Bakan SensÅ'') is a series of military engagements fought in 1863-64 , by joint naval force of
Great Britain,
France, the
Netherlands and the
United States, against the radical Japanese feudal domain of
ChÅshÅ«, along the banks of
Kanmon Straits off the cost of
Shimonoseki,
Japan.
Countdown to conflict
When Commodore
Matthew Perry of the
U.S. Navy sailed into
Edo (
Tokyo) Bay on
July 8,
1853 with his threatening ''kurofune'', the
Black Ships, demanding open trade with the West, two centuries of self-imposed
Japanese isolation (
Sakoku) came to an end. On
March 31,
1854 Japan signed the
Treaty of Kanagawa with the U.S. and later with other major European powers, granting them a series of exorbitant rights and powers. Intellectual Japanese widely regarded the treaty as unequal.
Despite efforts of appeasement by the
Tokugawa shogunate to establish an atmosphere of peaceful solidarity, many feudal ''daimyos'' remained bitterly resentful of the shogunate's open-door policy to the
West.
Belligerent opposition to Western influence erupted into open conflict when the
Emperor KÅmei, breaking with centuries of imperial tradition, began to take an active role in matters of state and issued on March 11th and April 11th 1863 his "
Order to expel barbarians" (攘夷実行ã®å‹…命). The Shimonoseki-based ChÅshÅ« clan, under Lord Mori Takachika, began to take actions to expel all foreigners after the date fixed as a deadline (May 10th, Lunar calendar). Openly defying the shogunate, Takachika ordered his forces to fire without warning on all foreign ships traversing
Shimonoseki Strait. This strategic but treacherous 112-meter waterway separates the islands of
Honshū and
Kyūshū and provides a passage connecting the Inland Sea with the
Sea of Japan.
Even before tensions escalated in Shimonoseki Strait, foreign diplomats and military experts, notably U.S. Foreign Minister to Japan
Robert Pruyn and Captain
David McDougal of the U.S. Navy, were aware of the precarious state of affairs in Japan. A letter to the Secretary of the Navy
Gideon Welles dated June 12, 1863 written by McDougal stated, "General opinion is that the government (of Japan) is on the eve of revolution, the principal object of which is the expulsion of foreigners.".

"Revere the Emperor and expel the barbarians!"
The ChÅshÅ« clan was equipped with mostly antiquated cannons firing cannonballs, but also some modern armament, such as five 8-inch
Dahlgren guns which had been presented to Japan by the United States, and three steam warships of American construction: the bark ''Daniel Webster'' (six guns), the brig ''Lanrick'' (''Kosei'', with ten guns), and the steamer ''Lancefield'' (''Koshin'', of four guns).

The first attack occurred on June 25, 1863. The U.S. merchant steamer ''Pembroke'', under Captain Simon Cooper, was riding anchor unsuspectingly outside Shimonoseki Strait, when intercepted and fired upon by two European-built warships belonging to the rebel forces. The crew of one enemy vessel taunted the frantic American seamen with the loud and unnerving cry, "Revere the Emperor and drive out the barbarians!" ("尊皇攘夷", pronounced "
SonnÅ JÅi"). Under incessant cannon fire, ''Pembroke'' managed to get underway, and escaped through the adjacent Bungo Strait, miraculously with only slight damage and no casualties. Upon arrival in
Shanghai, Cooper filed a report of the attack and dispatched it to the U.S. Consulate in
Yokohama, Japan.

Attack on the French warship ''Kienchang''.
Next day, June 26, the French naval dispatch steamer ''Kienchang'' was also riding anchor outside the strait, when rebel Japanese artillery atop the bluffs surrounding Shimonoseki opened fire on her. Damaged in several places, the French vessel was lucky to get away with but one wounded sailor.
On July 11, despite warnings from the crew of the ''Kienchang'', whom they had rendezvoused with earlier, the 16-gun Dutch warship ''Medusa'' cruised into Shimonoseki Strait. Her skipper, Captain
François de Casembroot was convinced that Lord Mori would not dare fire on his vessel, due to the strength of his ship and longstanding relations between the Netherlands and Japan. But Takachika did just that, pounding ''Medusa'' with more than thirty shells and killing or wounding nine seamen. De Casembroot returned fire and ran the rebel gauntlet at full speed, fearful of endangering the life of the Dutch Consul General, who was on board ''Medusa'' that time.
Within a short time, the Japanese warlord had managed to fire on the flags of most of the nations with consulates in Japan.
Despite retaliatory action from the treaty powers, another attack occurred in July, 1864, when the rebel forces fired upon the U.S. steamer ''Monitor'' after she entered a harbor for coal and water. This provoked further outrage, even after a British squadron was returning to Yokohama after delivering a multi-national ultimatum to Takachika, threatening military force if the strait was not opened.
The first battles
The coastal waters off
Shimonoseki were no stranger to bloodshed. At the watershed naval
Battle of Dan-no-ura on
April 25,
1185, a major engagement in the
Genpei War which was fought in the strait, a fleet belonging to
Minamoto Yoshitsune of the Genji clan wiped out the navy of rival Heike warlord
Taira Kiyomori.
American intervention

The
USS ''Wyoming'' battling in the Shimonoseki Straits against the Choshu steam warships ''Daniel Webster'' (six guns), the brig ''Lanrick'' (''Kosei'', with ten guns), and the steamer ''Lancefield'' (''Koshin'', of four guns).
Main articles: Naval battle of Shimonoseki
In the morning of July 16, 1863, under sanction by Minister Pruyn, in an apparent swift response to the attack on the ''Pembroke'', the U.S. frigate
USS ''Wyoming'' under Captain McDougal himself sailed into the strait and single-handedly engaged the US-built but poorly manned local fleet. For almost two hours before withdrawing, McDougal sank one enemy vessel and severely damaged the other two, along with some forty Japanese casualties, while the ''Wyoming'' suffered extensive damage with fourteen crew dead or wounded. The two Japanese steamers sunk by the ''Wyoming'' were raised again by ChÅshÅ« in 1864 and attached to the harbor of
Hagi.
French intervention
On the heels of McDougal's engagement, two weeks later a French landing force of two warships, the ''Tancrède'' and the ''
Dupleix'', and 250 men under Captain
Benjamin Jaurès swept into Shimonoseki and destroyed a small town, together with at least one artillery emplacement.
British intervention
On August 14, 1863, a British naval squadron led by Vice Admiral
Sir Augustus Kuper further swept into territory of the
Satsuma clan in the
Bombardment of Kagoshima, leaving behind the burning town of
Kagoshima and three sunken enemy steamers in its wake, at a cost of sixty-three British killed.
Diplomatic row

Meanwhile, the Americans, French, British and Dutch feverishly opened diplomatic channels in an effort to negotiate the reopening of the passage to the Inland Sea. Months dragged by with no end in sight to the growing dilemma.
By May 1864, various bellicose Japanese factions had destroyed thousands of dollars in foreign property, including homes, churches and shipping. This wanton destruction included the U.S. Legation in
Tokyo, which housed Minister Pruyn.
Throughout the first half of 1864, as Shimonoseki Strait remained closed to foreign shipping, threats and rumors of war hung in the air, while diplomatic efforts remained deadlocked. Then the British Minister to Japan Sir
Rutherford Alcock discussed with his treaty counterparts the feasibility of a joint military strike against Takachika. They were soon making preparations for a combined show of force. Under the wary eyes of the Japanese, fifteen British warships rode anchor alongside four Dutch vessels, while a British regiment from Hong Kong augmented their display of military might. The French maintained a minimal naval presence, with the bulk of their forces in
Mexico trying to bolster
Maximilian's unstable regime.
In the meantime, the insurgent prince procrastinated in negotiations by requesting additional time to respond to the allied demands, a course of action unacceptable to the treaty powers. The allies decided that the time for united action had arrived.
Final engagement and outcome

On August 17, 1864, a squadron consisting of nine British, five Dutch and 3 French warships (among them the
''Dupleix'') together with 2,000 soldiers steamed out of Yokohama to open Shimonoseki Strait. The U.S. chartered steamer, the ''Takiang'' accompanied the operation, in a token show of support. The two-day battle that followed on September 5 and 6 did what the previous operations could not: it destroyed the Prince of Nagato's ability to wage war.
Unable to match the firepower of the international fleet, and amid mounting casualties, the rebel ChÅshÅ« forces finally surrendered two days later on September 8, 1864. Allied casualties included seventy-two killed or wounded and two severely damaged British ships.
The stringent accord drawn up in the wake of the ceasefire, and negotiated by U.S. Minister Pruyn, included an indemnity of $3,000,000 from the Japanese (an amount equivalent to the purchase of about 30 steamships at that time).
[2] The
Bakufu proved unable to pay such an amount, and this failure became the basis of further foreign pressure to have the Treaties ratified by the Emperor, the harbor of
HyÅgo opened to foreign trade, and the customs tarifs lowered uniformly to 5%.

A full and interesting account is contained in Sir
Ernest Satow's ''A Diplomat in Japan''. Satow was present as a young interpreter for the British admiral, Sir
Augustus Kuper on the British flagship
HMS ''Euryalus''. It was also the action at which
Duncan Gordon Boyes won his Victoria Cross at the age of seventeen. Satow described Boyes as receiving the award "for conduct very plucky in one so young." Another VC winner at Shimonoseki was
Thomas Pride, and the third was the first American to win the medal,
William Seeley. De Casembroot wrote his account of the events in ''De Medusa in de wateren van Japan, in 1863 en 1864''.
In 1883, twenty years after the first battle to reopen the strait, the United States quietly returned $750,000 to Japan, which represented its share of the reparation payment extracted under the rain of multi-national shells.
Several life-size replicas of the guns used by ChÅshÅ« (probably the same as the ones in the image above) are now to be found at Shimonoseki in the spot where they were captured. They were put there by the Shimonoseki city government in 2004, in recognition of the importance of the bombardment in Japanese history. (The replicas are made of hollow steel and include coin-operated sound effects and smoke from the barrels.)
Historical significance

Les Invalides,
Paris. Inset: the symbol mark (
mon) of
ChÅshÅ« inscribed on top of the cannon.
Closely resembling the series of little conflicts fought by the Western powers in Asia, Africa and elsewhere during the Nineteenth Century, the troubles in Japan seemed to exemplify their
gunboat diplomacy, a prevalent tool in imperialism. Bitter resentment against foreign influence made the ChÅshÅ« clan feel justified in engaging in foolish acts of military provocation, in defiance of their own government. (The same nationalistic anger directed against foreigners demonstrated by the Japanese would flare up again in the Chinese
Boxer Rebellion.) The U.S. and its European allies then felt compelled to use military force to uphold the treaty with Japan.
For the U.S., July
1863 was a momentous month for Northern arms at
Gettysburg and
Vicksburg. While it was bitterly embroiled in the
Civil War, the world was carefully watching President
Abraham Lincoln's government for signs of weakness and indecision. The actions of ''USS Wyoming'' made it the first foreign warship to offensively uphold treaty rights with Japan; this fact coupled with the possibility that the events would mire the U.S. in a foreign war made the battle of Shimonoseki a significant engagement.
While the battles of Shimonoseki Strait were mere footnotes in the histories of the European powers, an interesting aspect of the affair was the resourcefulness displayed by the Japanese, something another generation of Westerners, eighty years later would come to appreciate. The feudal Japanese did not set eyes on a steam-powered ship until Commodore Perry's arrival, only a decade before ''USS Wyoming's'' battle. Yet they had rapidly learned the ways of the West within that brief span, purchasing foreign vessels and arming them with foreign weaponry. The quality and abundance of these armaments in 1860s Japan shocked the world.
