AD 1585 June : Dosetsu passed away in illness during the Siege of Yanagawa Castle.


According to the early Edo Period's military literature The Rise and the Fall of the Otomo Clan (<大友興廃記>) :

"Dosetsu's corpse was escorted to the Tachibana Castle by 1,000 men. Not a samurai from any hostile clan stopped the column, and paid him with great respect by letting them pass without molestation."

This famous Sengoku general won the widespread fame recorded in historical archives as the following paragraph extracted from the Japanese wikipedia. I'll translate it later (I am already exhausted just after finishing the chronicles alone...).

道雪は孫子兵法の「奇正相生」を引用して、家臣の由布惟信と小野鎮幸を招いて曰く: 「軍勢を用いるには、先ず戦法を定め、勇武の勢と共に奇・正の変化をさせるがよい。お前達両名が替わる替わる奇・正の将となって自分を補佐せよ。凡そ戦というものは正法を以って引き分けとし、奇法を以って勝ちとする。それで、正法を行う者は江河のように渇れることがなく、奇法をよく行う者は天地にように無窮である。故に、奇・正両法を用いる者は戦って勝たないという事が無い。それで、今日から両名には正・奇の戦法を取って貰いたい。今日惟信が正軍の将であるなら、鎮幸が奇軍の将となり、明日はそれを替えるという様にせよ。副将には、薦野増時、米多比鎮久をそれぞれ当てよう。」 と、立花家の戦は常に奇襲と正攻法を連携して、九州において常勝不敗と伝われました。 こうして毛利軍との戦いで勝利を重ねた道雪は、毛利家の興亡を焦点にしている軍記物である『陰徳太平記』で「道雪は大友家に肩を比ぶる者なきのみか、隣国にも亦類少き士大将にて、智謀尭捷兼達し、堅を砕き、利を破り、奇正応変に過ちなく」と賞賛されている。現代語にするなら「道雪はいかなる状況でも的確な判断を行ない、臨機応変に対処できる、戦国屈指の名将だ」と褒め称えているのである。


Tachibana Dosetsu was certainly no inferior than other far more famous great men like Takeda Shingen, Uesugi Kenshin, Hojo Ujiyasu, Oda Nobunaga in the field of military command. Yet he was pretty much an "obscure" figure in the Westerners' recognition, along with his equally-great son Tachibana Muneshige (立花宗茂). Next time I'll focus on analyzing several of the military campaigns involved with Dosetsu's direct participation for assessing his military leadership, to evaluating is he really worthy to be on the list of one of the greatest military commanders in the world history.
