The path they walked

1536

Raised as Nobunaga's foster brother

He was born the son of Ikeda Tsunetoshi, a retainer of the Oda house in Owari. His mother, Yōtoku-in, became the wet nurse of Oda Nobunaga, so Tsuneoki grew up as Nobunaga's foster brother, nursed at the same breast, and spent his childhood at Nobunaga's side. His father is said to have died early, and Tsuneoki served Nobunaga as a page.

1557

Dealing with Nobukatsu's plot

Nobunaga's younger brother Nobukatsu (Nobuyuki), accused of plotting rebellion again, was killed at Kiyosu Castle. Tsuneoki is said to have been one of those who struck him down on Nobunaga's orders. This shows that, as a retainer bound closely to Nobunaga, he was entrusted even with a grave family conflict.

1560

The Battle of Okehazama

He took part in the Battle of Okehazama, where Nobunaga defeated the great army of Imagawa Yoshimoto with a small force. This victory secured Nobunaga's position in Owari and launched his rise, and Tsuneoki followed him as a retainer into campaigns in Mino and elsewhere.

1561

The Battle of Karumi

At the Battle of Karumi against the Saitō of Mino, he and Sassa Narimasa killed an enemy commander. This is the first scene in which Tsuneoki clearly appears in the Chronicle of Lord Nobunaga, written by one of Nobunaga's retainers. Nobunaga's campaign against Mino continued for several more years.

1570

Anegawa and lordship of Inuyama

He fought well at the Battle of Anegawa against the Azai and Asakura and became lord of Inuyama Castle in Owari. He went on to take part in the burning of Mount Hiei and the fighting against the Ikkō uprising at Nagashima in Ise, serving across the land as one of the generals supporting Nobunaga's unification.

1574

Supporting Nobutada in eastern Mino

When Takeda Katsuyori seized Akechi Castle in Mino, Tsuneoki entered Ori Castle in eastern Mino under Nobunaga's heir Oda Nobutada and strengthened its defences. Also charged with supporting Nobutada, the future head of the house, he was given the important task of guarding the border with the Takeda.

1578

Araki Murashige's revolt and Settsu

When Araki Murashige of Settsu rebelled against Nobunaga, Tsuneoki went to Settsu with his eldest son Motosuke and second son Terumasa and joined the siege of Arioka Castle. He later captured Hanakuma Castle and, after the war, was given Itami Castle and lands in Settsu.

1582

The Battle of Yamazaki

When Nobunaga was killed in the Honnō-ji Incident, Tsuneoki kept the warriors of Settsu from joining Akechi Mitsuhide. He joined Hashiba Hideyoshi, who had hurried back from the west, shaved his head and took the name Shōnyū. At the Battle of Yamazaki he led the vanguard of the right wing and defeated Mitsuhide's army.

1582

The Kiyosu Conference

He attended the Kiyosu Conference on Nobunaga's succession and lands, together with Shibata Katsuie, Niwa Nagahide and Hashiba Hideyoshi. As one of the four senior retainers of the Oda house he received Osaka, Amagasaki and Hyōgo in Settsu. From then on he sided with Hideyoshi.

1583

Moving to Ōgaki in Mino

After Hideyoshi defeated Shibata Katsuie, Tsuneoki moved to Ōgaki Castle in Mino, while his eldest son Motosuke took Gifu Castle and his second son Terumasa Ikejiri Castle. He also agreed to marry his daughter to Hideyoshi's nephew, the future Toyotomi Hidetsugu, tightening his ties with Hideyoshi.

1584

His end at Nagakute

In the Battle of Komaki and Nagakute, fought between Hideyoshi and Tokugawa Ieyasu with Oda Nobukatsu, Tsuneoki led the vanguard of a detached force meant to strike at Mikawa. Defeated by the Tokugawa army at Nagakute, he fell on the battlefield together with his eldest son Motosuke and his son-in-law Mori Nagayoshi. His second son Terumasa succeeded him and later became lord of Himeji Castle.
