原文：

昔者张中丞守睢阳，贼兵围之数重，城中粮尽，援军未至。然中丞意气自若，与将士同甘共苦。贼军屡攻不下，终因粮绝而退。中丞之勇毅，实乃千古楷模。后世之人，当以此为鉴，知忠诚之可贵，勇毅之难得。

翻译：

In ancient times, Zhang Zhongcheng defended Suiyang against the enemy forces that surrounded it on all sides. The city was running out of food, and no reinforcements had arrived yet. Nevertheless, Commander Zhang remained calm and collected, sharing hardships with his soldiers. Despite repeated attacks by the enemy, they could not breach the defenses, and eventually withdrew due to lack of supplies. His bravery and steadfastness serve as an exemplary model for all generations. Posterity should take this as a lesson, understanding the preciousness of loyalty and the rarity of such courage.

以上便是《张中丞传》后叙的部分内容及其翻译。通过这段文字，我们可以感受到张巡等人在困境中的坚韧不拔以及他们对国家的忠诚之心。这些品质值得我们每一个人学习和传承。
