太子申 / Prince Shen of Wei
太子申 / Prince Shen of Wei appears in 《资治通鉴·周纪》19丨马陵之战 when 魏国 responds to 齐国’s advance toward 大梁. 庞涓 is recalled from the Han front, and Wei raises another army under Prince Shen.
The episode uses this appointment to explain 太子挂帅风险. A crown prince is politically valuable as the stabilizing heir, but dangerous as a field commander because military reputation, officer networks, and inheritance legitimacy can converge in one person.
《资治通鉴·周纪》20丨庞涓死此树下 completes Prince Shen’s battlefield role. After 庞涓 dies in the Maling ambush and the Wei army falls into disorder, 齐国 breaks the Wei force and captures Prince Shen. This makes the earlier command-risk warning concrete: the heir is not only politically sensitive as a commander, but exposed to capture when the campaign collapses.
