The general who advances without coveting fame and retreats without fearing disgrace, whose only thought is to protect his country and do good service for his sovereign, is the jewel of the kingdom.
Giles’s translation, Chapter X §24. The Chinese literally runs closer to “advances without seeking fame, retreats without shunning blame, whose sole care is to protect the people to the sovereign’s benefit — he is the treasure of the state.”

The underlying Chinese text is ancient and long in the public domain. The exact English wording shown is Lionel Giles’s translation, first published in 1910 — well before 1931 — so this translation is also in the public domain in the United States. Later translations (e.g. Griffith 1963, Cleary 1988) remain in copyright, but their wording differs from this one.
⚠ This reflects the original work, which is public domain. If your exact English wording comes from a specific modern translation, that translation may itself still be under copyright — check the edition you quote.
