Purpose The purpose of this paper is to explore a true World War One event, the Christmas Truce of 1914. The paper is inspired by the National Council for the Social Studies (NCSS) award winning book, Shooting at the Stars: The Christmas Truce of 1914 by John Hendrix, which narrates the truce through a fictitious letter from a British soldier. On Christmas Eve, German soldiers on the western front line, specifically near the Belgium border, ceased fire and invited British soldiers to celebrate Christmas. Descriptions of events derive from oral histories and photos collected from actual soldiers who experienced this unusual historic event. Design/methodology/approach This lesson engages students in inquiry centers focused on events, location, soldiers, remembrance, and primary sources to answer the question: Why did the First World War Christmas Truce of 1914 occur? Practical implications World War One (AKA the First World War and The Great War) classroom history studies typically focus on tragic components of, what many call, a needless war. Many lessons examine military technologies, political power struggles, horrors of trench warfare, disease and casualties. In essence, “World War I saw unprecedented levels of carnage and destruction. By the time the war was over and the Allied Powers claimed victory, more than 16 million people – soldiers and civilians alike – were dead” (history.com Staff, 2009). This lesson reveals a spontaneous, impactful, emotionally charged event occurring during the worst of times. The Christmas Truce of 1914 moves students from thinking about the ravages of war into thinking deeply about what it truly means to be enemies, friends or even to mend relationships. Who are soldiers – what do they feel, need, believe and miss? During the truce, the longing for peace and human interaction superseded political ideologies, for a while. This lesson starts with students participating in a class discussion to uncover prior knowledge of the famous event. Students examine their real-life feelings regarding personal truces, answer guiding questions while rotating through classroom research centers, and collectively create a generalized response to answer the compelling question: Why did the First World War Truce of 1914 occur? Students will apply their understandings of the event, location, and feelings associated with the truce by taking a soldier’s persona and writing a letter home. Illustrations and maps further engage students’ creativity. Social implications This true story about the Christmas Truce of 1914 reminds us that countries may have differing ideologies and political beliefs which cause conflicts, yet people, as individuals, find commonalities making them seek peaceful connections with one another. Originality/value “The soldiers of 1914 remind us of the choice we all can make: we can see others as humans who matter like we matter – even when they’re our enemies. They also show us what can happen when we make that choice: enemies can become friends and, at least for a moment, there is peace” (Arbinger Institute, 2017, Section 3). This quote embodies the lesson’s value, because it brings understanding to a personal level – soldiers on the field. First World War soldiers were typically powerless. For instance, as many as 250,000 boys under the age of 18 served in the British army during the First World War. Patriotic fervor, escape from poor conditions or hopes for adventure were motives for joining. Birth certificates were uncommon; war recruiters received money for each sign-on, so boys as young as 14 went to war. In this lesson, students examine First World War background information; analyze the truce’s events, geography, soldiers and memorials. Students are immersed in large numbers of resources including videos, music, photographs, maps, books, articles, newspapers, historians’ perspectives, oral histories, museum archives and the First World War soldiers’ original letters that help reveal the story and help students understand underlying feelings of soldiers and their families.
