Ma Yu

Biography & Historical Record

Ma Yu (马玉, Mã Ngọc) is a Shu Han officer who appears only as a name in a casualty list. In Romance Chapter 97 Zhuge Liang, asking the Later Lord for a second campaign, quotes (or the novel quotes for him) the Later Chu Shi Biao: since the army reached Hanzhong, “we have already lost Zhao Yun, Yang Qun, Ma Yu, Yan Zhi, Ding Li, Bai Shou, Liu He, Deng Tong, and more than seventy company and colony captains,” plus a thousand of the old Cong, Sou, and Qing Qiang horse. The argument is demographic: these men were decades of gathered talent, not one province’s surplus; wait a few more years and two-thirds will be gone. Ma Yu is never given a courtesy name, a home commandery, a duel, or a death scene. He is one of the “already dead” whom the memorial needs in order to say that delay is itself a kind of defeat.

This is not Ma Yu (马宇) of the Eastern Han on /ma-yu-han/, and not Ma Yuanyi (马元义) of the Yellow Turbans. The 汉字 here is 玉 (jade), not 宇. Chen Shou’s own Sanguozhi does not give Ma Yu a biography. The Later Chu Shi Biao itself is transmitted by Pei Songzhi from Xi Zuochi’s Han Jin Chunqiu, which cites Zhang Yan’s Moji; many scholars doubt Zhuge Liang wrote it. Historically, then, Ma Yu is a name on a possibly later memorial — still the only source that knows him. Treat the loss as real inside the novel’s second-expedition debate, and as uncorroborated outside it.

Role in Romance of the Three Kingdoms

Chapter 97 (The Martial Marquis Submits a Second Memorial; Jiang Wei Breaks Cao’s Army with a False Letter): It is Jianxing 6, autumn. Lu Xun has smashed Cao Xiu at Shiting; Zhuge Liang wants the opening. The Later Lord is surrounded by caution. The memorial — the Later Chu Shi Biao — answers six “I do not yet understand” objections. The fifth is the butcher’s bill since Hanzhong: Zhao Yun (赵云, Triệu Vân) is already gone (Chapter 96), and with him Yang Qun (阳群, Dương Quần), Ma Yu (马玉, Mã Ngọc), Yan Zhi (阎芝, Diêm Chi), Ding Li (丁立, Đinh Lập), Bai Shou (白寿, Bạch Thọ), Liu He (刘郃, Lưu Hợp), Deng Tong (邓铜, Đặng Đồng), the seventy-odd captains, and the non-Han horse. If the state waits, it will not have an army left to wait with. The Later Lord yields; the rest of the chapter is the failed Chencang road, Wang Shuang, and Jiang Wei’s false letter to Cao Zhen (曹真, Tào Chân). Ma Yu does not ride in any of those later movements. He is already a number in paragraph five.

Ma Yu (马玉) — Historical & Literary Timeline

The list lives in the Chu Shi Biao tradition (Later memorial).

Key Relationships

Family

• None recorded. Not a brother of Ma Chao’s house and not the Han official 马宇 on /ma-yu-han/.

Friends

• Zhuge Liang (诸葛亮, Gia Cát Lượng): The commander in whose Hanzhong year Ma Yu is said to have died; the memorial uses that death as an argument, not as a eulogy with a story.
• Yang Qun (阳群, Dương Quần), Yan Zhi (阎芝, Diêm Chi), Ding Li (丁立, Đinh Lập), Bai Shou (白寿, Bạch Thọ), Liu He (刘郃, Lưu Hợp), Deng Tong (邓铜, Đặng Đồng): Fellow names on the same casualty line — catalogue comrades, not a sworn set.

Enemies

• Wei in the abstract. No officer is named as Ma Yu’s killer. The Chapter 97 living antagonists (Cao Zhen (曹真, Tào Chân), Wang Shuang) belong to the campaign after he is already listed as lost.

Other

• Zhao Yun (赵云, Triệu Vân): First and most famous name on the same memorial list; his death in Chapter 96 is the only one the novel has already staged.
• Jiang Wei (姜维, Khương Duy): The man whose false letter occupies the second half of Chapter 97 — same chapter, later scene, no personal link to Ma Yu.
• Wrong slug: /ma-yu-han/ = 马宇 (Eastern Han). /ma-yuanyi/ = 马元义. This post is 马玉 only.
