Tsuneoki Ikeda

A military commander in the Azuchi-Momoyama period. According to the "Abridged History of the Ikeda Family" (published by the Okayama Prefectural Local Culture Foundation), "Lord Nobuteru was originally Tsuneoki, his childhood name was Shosaburo, he shaved his head and became Lord Shonyu, and his posthumous title was Gokokuin." Regarding "Nobuteru," the "Ikeda Akimasa (12th Lord of Okayama Domain) Family Genealogy" (Ikeda Family Library) states, "He distinguished himself in the Battle of Okehazama, was given the surname by Nobunaga, changed his name to Nobuteru, and became a warrior general," but his name is not found in any old documents or high-quality materials from that time. While his father, Ikeda Tsunetoshi, was a ronin, his mother, Yotokuin, became Nobunaga's wet nurse, and he served Nobunaga. It is said that Nobunaga was able to become a wet nurse because he only bit Yotokuin's breast and did not tear it. He distinguished himself in the Battle of Okehazama in 1560 (Eiroku 3), and was awarded Inuyama Castle in Owari Province in 1570 (Genki 1). In 1579 (Tensho 7), he defeated Araki Murashige in Settsu, and was awarded the castles of Arima, Amagasaki, and Hanakuma. After the Honnoji Incident in 1582, he defeated Akechi Mitsuhide together with Hashiba Hideyoshi, and became a senior retainer, administering Kyoto. He was awarded 100,000 koku in Settsu Province and resided in Osaka Castle. In the Battle of Shizugatake the following year, he joined Hideyoshi and defeated Shibata Katsuie, and was awarded 130,000 koku in Mino Province. In 1584, Oda Nobukatsu and Tokugawa Ieyasu set up camp at Komakiyama, and came into conflict with Hideyoshi. Tsuneoki, who sided with Hideyoshi, proposed a strategy to capture Okazaki and attack Ieyasu from both sides, and was employed. He advanced with Toyotomi Hidetsugu as commander-in-chief, but Hidetsugu's forces were destroyed in a surprise attack by Ieyasu's troops, and Tsuneoki was killed in battle at Nagakute along with the forces of his eldest son, Motosuke, and his son-in-law, Mori Nagayoshi.

安土桃山時代の武将。『池田家履歴略記』（岡山県郷土文化財団本）によると、「信輝(のぶてる)公初めは恒興、幼名勝三郎(しょうさぶろう)、剃髪(ていはつ)して勝入(しょうにゅう)公、諡号(しごう)を護国院」と記されている。「信輝」については『池田章政（12代岡山藩主）家譜』（池田家文庫）に「桶狭間(おけはざま)の戦に有功、信長より名字を授かりて、信輝と改め士大将となる」と記されているが、当時の古文書や良質の資料には、その名はみられない。父、池田恒利が浪人中、母、養徳院が織田信長の乳母となったことから信長に仕える。信長は養徳院の乳房のみ噛(か)み破らなかったから乳母になれたという。1560年（永禄3）桶狭間の戦いで功を上げ、1570年（元亀1）尾張国犬山城を与えられる。1579年（天正7）摂津で荒木村重を倒し、有馬(ありま)、尼崎、花隈(はなくま)の諸城を与えられる。1582年本能寺の変後、羽柴秀吉とともに明智光秀を討ち、宿老に列し京都の施政にもあたり、摂津国内10万石を与えられ大坂城に在城。翌1583年の賤ヶ岳(しずがたけ)の戦いには、秀吉に属し柴田勝家を破り、美濃国13万石を与えられる。1584年織田信雄(おだのぶかつ)・徳川家康らが小牧山に陣をしき、秀吉と対立。秀吉方に属した恒興は、家康を挟撃する岡崎攻略作戦を献策し用いられ、豊臣秀次を総大将として進軍するが、家康軍の奇襲で秀次軍が崩壊し、恒興も嫡男元助(もとすけ)や女婿森長可(もりながよし)勢らとともに長久手(ながくて)で戦死した。
