It is said that he was called Binwari (jar crushing) Shibata because he crushed a water jar and encouraged his troops by shouting 'Men, it is the honor of a samurai to die on the battlefield rather than to die of thirst, so remember, the water you just had was your matsugo-no-mizu (water of the last moment)!' to approach the resistance by burning their boats while holding Choko-ji Castle (this is believed to be a later creation).
長光寺城に籠城中、水瓶を割って、「貴様ら、乾いて死ぬよりも討死にするが武士の誉れぞ今飲んだ水が末期の水と知れい！」と叱咤激励し、背水の陣で抗戦に臨んだことから瓶割り柴田と呼ばれるようになったと言われている（これは後世の創作だと思われる）。
