Previously

In 342, King Gogugwon of Goguryeo saw his capital trampled by Former Yan and even lost his father King Micheon’s body before winning it back. In 371, while holding off the Baekje army at Pyongyang Fortress, he was struck down by an arrow, and his son, King Sosurim, rebuilt the kingdom with Buddhism, the Taehak and law codes. The Baekje king who attacked that Pyongyang Fortress is the hero of this episode.

King GogugwonKing of Goguryeo.
His name is Sayu

In 346, the second son of King Biryu took the throne of Baekje. He was King Geunchogo.

The Samguk Sagi described him as “remarkable in build and looks, with far-reaching insight.”

King GeunchogoKing of Baekje

MoruI’m Moru. I make my living hammering iron in the Baekje capital.

MoruThe more you hammer iron,
the harder it gets.
GeungusuSon of King Geunchogo · Crown prince of Baekje
Crown Prince GeungusuCan you make a sword
with seven branches?
MoruSeven… branches?
You can’t fight with a sword like that.
It’s not a sword
for fighting.

In the 9th month of 369, Sayu, King of Goguryeo (King Gogugwon), came south with 20,000 infantry and cavalry and made camp at Chiyang.

It’s the Goguryeo army!
Run!

The Goguryeo army split up its forces and raided the people’s homes.

Messenger20,000 Goguryeo troops
are ravaging Chiyang!
King GeunchogoCrown Prince, take the shortcut
and strike them!

When the crown prince’s troops reached Bangeolyang and were about to give battle, a man came over from the Goguryeo side.

SoldierThis one came over
from the Goguryeo camp!
SagiI’m… from Baekje,
originally!

Sagi was originally a man of Baekje.

He had accidentally injured the hoof of a royal horse and, fearing punishment, had fled to Goguryeo.

Mak Go-haeBaekje general
SagiThey may be many,
but most are just there to make up numbers.
The only real fighters
are the red-banner unit!
Break them first,
and the rest will fall apart on their own.
Crown Prince…The red banners, then.

The crown prince struck straight at the red-banner unit.

When the red banners fell, the Goguryeo army collapsed in a rout.

The crown prince pursued the fleeing enemy all the way to the land northwest of Sugok Fortress.

General Mak Go-haeYour Highness, I once heard the Daoists say,
“Know contentment and you avoid disgrace;
know when to stop and you avoid danger.”
You have already gained much.
Why seek more?

The crown prince saw the wisdom in his words and stopped. Then he had stones piled up there to mark the spot.

Crown PrinceAfter today, who will ever
come this far again!

The rock there had a crevice hollowed out like a horse’s hoofprint.

For a long time afterward, people called it “the Crown Prince’s Hoofprint.”

In the 11th month of that year, the king held a grand review of his troops south of the Han River. Every banner was yellow.

MoruI was there among the onlookers too. Under the yellow banners, the spearheads I had hammered flashed.

MoruThat year, I forged that sword. I folded the iron, hammered it, and folded it again.

MoruOnly iron forged a hundred times
keeps the branches from breaking.

MoruI carved characters into the blade and hammered gold wire into every groove.

MoruEvery character
is inlaid with gold wire.
Crown Prince…“Since ages past,
there has never been such a sword.”

It was a sword with three branches on each side of the blade, seven points in all.

MoruA sword to ward off
every weapon…

In 371, Goguryeo raised an army again. The king laid an ambush on the banks of the Pae River, and when the enemy arrived, he struck and drove them back.

That winter, the king and the crown prince led 30,000 crack troops toward Goguryeo’s Pyongyang Fortress.

King GeunchogoCrown Prince Geungusu
King GogugwonSayu, King of Goguryeo
King of GoguryeoDo not fall back!
Hold this fortress!

Sayu, King of Goguryeo, came out in person and fought hard to defend the fortress.

An arrow flew in and struck the King of Goguryeo.

MessengerThe King of Goguryeo…
has breathed his last, they say.
King Geunchogo…So he fell defending
his fortress to the very end.
Withdraw the troops.
We go home.

The King of Goguryeo died on the 23rd day of that month. King Geunchogo led his army back.

That year, the king moved his capital to Hansan.

In the 1st month of the next year, a Baekje envoy
set off across the sea to Eastern Jin.

In the 6th month of 372, the emperor of Eastern Jin in turn sent an envoy and named the king “General Who Guards the East and Governor of Lelang.”

a title on the King of Baekje.

While standing up to Goguryeo in the north, Baekje exchanged envoys with Eastern Jin across the sea.

MoruAround that time, a ship carrying the Seven-Branched Sword set out to sea.

MoruFarewell…
my light of seven branches.

The sword crossed the sea to Wa.

The inscription on the sword is usually read as saying that “the crown prince of Baekje made it for the King of Wa,” and many date its making to 369.

Yet the Nihon Shoki, a Japanese history compiled in the 8th century, records that a Baekje envoy “offered up” the Seven-Branched Sword to Wa.

A sword bestowed, a sword offered up, or a gift exchanged?
Opinions are divided even today.

According to an old record, it was around this time that Baekje gained the scholar Go Heung and first set down the affairs of the kingdom in writing.

Go HeungBaekje scholar
King GeunchogoLet those who come after us
know what we have done.

In the 7th month of 375, Goguryeo attacked and seized Sugok Fortress on the northern frontier.

Crown PrinceAfter today, who will ever
come this far again!
King GeunchogoI will raise a great army
and pay them back for this!

But a famine struck that year, and in the end he could not send out his army.

King GeunchogoLet those who come after us
know what we have done.

In the 11th month of 375, King Geunchogo died. Crown Prince Geungusu succeeded him.

Some 1,500 years later,

at a shrine across the sea,
a rusted sword came to light.

The 1870s: Isonokami Shrine in Nara Prefecture, Japan.

七支刀
Crown Prince…“Since ages past, there has never been such a sword.”

When Kan Masatomo, the head of the shrine, stripped the rust from the old sword, gold characters appeared.

The worn characters at the end of the back of the blade are usually read like this:

Hand it down and show it to generations to come.

The sword that crossed the sea from Baekje is still at Isonokami Shrine today.

History Notes

The scenes in this story are based on these records and sites.

  1. Chiyang and Bangeolyang

    The Samguk Sagi entry on King Geunchogo records that in the 9th month of 369, when Sayu, King of Goguryeo, camped at Chiyang with 20,000 infantry and cavalry and plundered the people’s homes, the crown prince rushed there by a shortcut, routed them and killed more than 5,000 of the enemy. The stories of Sagi’s tip-off, the red-banner unit, Mak Go-hae’s words and the cairn appear separately in the entry on King Geungusu, which calls the battlefield “Bangeolyang.” The two accounts are often taken to describe the same battle, but whether Chiyang and Bangeolyang are the same place is unknown. Chiyang is thought to be present-day Baecheon in Hwanghae Province, and Sugok Fortress the area around Singye, also in Hwanghae Province.

  2. The Wisdom of Knowing When to Stop

    The words Mak Go-hae quoted, “Know contentment and you avoid disgrace; know when to stop and you avoid danger” (知足不辱 知止不殆), are a passage from the Laozi (Daodejing). People are said to have called the hoof-shaped crack in the rock where the crown prince piled the stones “the Crown Prince’s Hoofprint.” The Samguk Sagi says it is still called that “to this day” (至今), but we cannot tell whether this “day” means the Goryeo period or the time of the older record the Samguk Sagi copied from. Yet six years later, in 375, Goguryeo seized that very Sugok Fortress.

    Samguk Sagi, Baekje Annals, King Geungusu
  3. Pyongyang Fortress, 371

    The Baekje Annals and the Goguryeo Annals agree that in the winter of 371 (the 10th month, according to the Goguryeo Annals), 30,000 Baekje troops attacked Pyongyang Fortress and the King of Goguryeo was killed by a stray arrow. The Baekje Annals write that he “fought hard to hold them off,” and the Goguryeo Annals that he died on the 23rd day of that month. Buried on the “Plain of Goguk,” he is called King Gogugwon. The words King Geunchogo speaks on hearing of his death are invented dialogue, not found in the records.

    The Seven-Branched Sword and Its Inscription

    The Seven-Branched Sword is an iron sword kept at Isonokami Shrine in Nara Prefecture, Japan. It is about 75 cm long, with three branches extending from each side of the blade. In the 1870s, Kan Masatomo, the head of the shrine, found 61 characters inlaid in gold on its front and back while removing the rust, but some characters are too worn to read easily, so readings differ from scholar to scholar. The date, “the 4th year of Tai□,” is widely taken to be the 4th year of Taihe of Eastern Jin (369), though some date it to 408 or 480. The blacksmith Moru and his apprentice who forged the sword, and the scene of Crown Prince Geungusu (widely seen as the “crown prince” of the inscription) visiting the smithy, are imagined and not found in the records.

    Who Gave the Sword to Whom?

    The entry for the 52nd year of Empress Jingū in the Nihon Shoki says that a Baekje envoy “offered up” the Seven-Branched Sword and a seven-child mirror to Wa (many scholars shift the book’s dates 120 years later and place this in 372). But the sword’s inscription is usually read as saying that “the crown prince of Baekje made it for the King of Wa,” so interpretations are divided: a sword offered as tribute (the tribute theory), a sword bestowed by the King of Baekje (the bestowal theory), a gift between equals, a sword granted by Eastern Jin by way of Baekje, and so on. Because the Nihon Shoki has many passages that embellish dealings with the Korean Peninsula to put Wa at the center, scholars read it critically, comparing it with other records. Many scholars reinterpret the story of a southern campaign in the entry for the 49th year of Empress Jingū in the same book as King Geunchogo’s absorption of the Mahan lands in the south, but opinions differ on how far that went.

  6. An Eastern Jin Title and Go Heung’s Seogi

    The Samguk Sagi records that in the 1st month of 372 Baekje sent an envoy across the sea to Jin (Eastern Jin), and the Book of Jin reports that in the 6th month of that year Eastern Jin named the King of Baekje, “Yeogu (餘句),” General Who Guards the East and Governor of Lelang. Since Lelang Commandery had already ceased to exist in 313, the title is seen as a purely nominal one rather than a post over territory he actually ruled. The Samguk Sagi, citing an old record, also says that around this time Baekje gained the scholar Go Heung and for the first time came to have the Seogi, but Kim Bu-sik added that he did not know who Go Heung was, since he appears in no other book.

    Hansan and the Remains of Hanseong

    The Samguk Sagi records that in 371 King Geunchogo “moved the capital to Hansan,” but opinions differ on where Hansan was and whether the capital really moved. Many believe the heart of the Baekje capital at this time was the area of Pungnap Earthen Fortress and Mongchon Earthen Fortress, south of the Han River. Some see the large stone-mound tomb (Tomb No. 3) in Seokchon-dong, Seoul, as King Geunchogo’s tomb, but this is not certain.
