The preface to Why We Are at War establishes a distinctive authorial stance: the contributors are historians, not politicians, and they belong to different schools of political thought. They aim to treat the subject historically, drawing on firsthand evidence from the British and German White Books. The second edition, revised in September 1914, incorporates the Russian Orange Book, and the authors note they have modified sentences in light of that new evidence. This careful, document-based approach shapes the entire work.

A Historians' Brief, Not a Politician's Speech

The preface explicitly distances the authors from political advocacy: 'We are not politicians, and we belong to different schools of political thought.' Instead, they claim expertise in handling historic evidence and promise to treat the subject historically. This framing is crucial for a first reading, as it signals that the book will rely on documentary proof rather than rhetorical appeals. The authors also disclose their sources—the British White Book (Cd. 7467) and the German White Book—and note that they have reproduced the German White Book in full, including its uncorrected English solecisms. This transparency about sources invites readers to evaluate the evidence themselves.

The German White Book as a Central Exhibit

A substantial excerpt from the German White Book appears in the text, presenting the German government's account of the July crisis. The document includes detailed diplomatic exchanges: the Russian Secretary of War giving his 'word of honor' that no mobilization order had been issued, and the German ambassador warning that 'mobilization means war.' The German narrative emphasizes that Russia's military preparations forced Germany's hand. Readers should note that this is an official apology, as the preface states, and that the authors have printed it 'in extenso' for scrutiny. The inclusion of this document allows direct comparison with the British documents quoted elsewhere.

The Role of Belgium and the Treaty of 1839

The table of contents reveals that Chapter I addresses 'The Neutrality of Belgium and Luxemburg,' tracing the origin of Belgian neutrality and the Treaty of 1839. The preface also mentions that profits from the book will go to the Belgian Relief Fund, as 'a mark of sympathy and respect for the Belgian nation, and especially for the University of Louvain.' This connection between the book's argument and a concrete charitable act underscores the moral weight the authors attach to Belgium's violation. For a first reading, this chapter likely provides the legal and historical foundation for the British case, arguing that Germany's invasion breached a treaty to which Britain was a guarantor.

Appendix of Original Documents as Evidence

The book includes appendices with original documents: the German White Book (Appendix), the Russian Orange Book (Appendix VI), and a selection from the British White Book. The preface explains that the Russian Orange Book was added for the second edition, allowing the authors to modify earlier sentences. This documentary apparatus is central to the book's method. Readers should treat these appendices as primary sources that the authors interpret in the main text. The inclusion of multiple national documents—German, British, Russian—encourages a comparative approach, though the authors' own argument clearly sides with the British interpretation.

Reading Why We Are at War as a historical document from September 1914, rather than as a definitive account, reveals how contemporary scholars marshaled evidence to justify a controversial decision. The book's value lies not in its objectivity—the authors are openly partisan—but in its method: it invites readers to examine the same documents the authors used and to weigh the competing narratives. Pay close attention to how the authors frame the German White Book as an 'apology' and how they integrate new evidence from the Russian Orange Book.
