Happy Latin: Caesar's Battles is a 28-hour bilingual (English + 中文) first-year Latin course built around Julius Caesar's De Bello Gallico. Each hour pairs an episode from the Gallic war (or an excursus from Tacitus, Suetonius, or Plutarch) with one chapter of Wheelock's Latin (6th edition revised, LaFleur 2005). The course traces fourteen years — from the Helvetii crossing the Arar (58 BC) to Caesar's assassination on the Ides of March (44 BC) — across all 8 books of DBG and a closing capstone drawn from the biographical tradition. 《快乐拉丁语：凯撒的战役》是一门 28 课时的双语（English + 中文）一年级拉丁语课程，围绕凯撒《高卢战记》构建。每课时将一段高卢战争之事件（或塔西陀、苏埃托尼乌斯、普鲁塔克的旁注）与韦洛克拉丁语（第六版修订，LaFleur 2005）的一章相配。课程跨越十四年，自赫尔维提人公元前 58 年跨越阿拉河，至凯撒公元前 44 年三月之中遇刺，读完《高卢战记》全八卷，外加取自传记传统的收束总章。
