A decision under uncertainty
Could a different decision at Ypres have changed the course of 1917? This optional writing exercise asks you to build a plausible alternative without giving your imagined decision-makers knowledge of the future.
It is a creative exercise, not a prize competition. There is no submission deadline, judging panel or credit reward attached to this article.
Start with the historical record
The Third Battle of Ypres began on 31 July 1917 in Belgium. Douglas Haig sought a breakthrough from the Ypres salient; the wider plan looked towards the Belgian coast and the submarine bases there. Ypres was itself part of the Western Front, so attacking there and reinforcing that front were not two geographically separate choices. The National Army Museum's account explains the setting and objectives.
Rain, damaged ground and German resistance complicated the offensive. The campaign continued into November, and its achievements and costs remain subjects of historical debate. The Australian War Memorial's overview describes both the changing prospects for a breakthrough and the continuing aim of wearing down German forces.
Your imagined decision
For the exercise, place an invented planning discussion before the offensive begins. You are advising the British command, rather than acting as a single general with unlimited authority.
Choose one change: recommend a delay to the offensive, or propose more limited initial objectives. These are writing prompts, not claims that a particular meeting considered these exact alternatives.
Explain what your proposal aims to achieve. What resources would it require? How might other commanders or allies respond? What would make the proposal fail?
Build consequences one step at a time
Begin with the next few weeks rather than jumping straight to a different end to the war. Consider movement, supplies, troop readiness and the possibility that the opposing army adapts.
Do not assume that delaying an attack guarantees fewer casualties overall, or that capturing a position guarantees peace negotiations. Those outcomes need their own arguments. Keep at least one consequence unresolved: uncertainty makes the exercise more credible.
Then add a second perspective. How would your imagined change affect a soldier, a medical worker or a civilian? Label invented characters and dialogue as fiction, and avoid turning real suffering into a simple score for victory or defeat.
Check your scenario
Before sharing, distinguish three things in your writing: documented events, your chosen point of divergence, and the consequences you have invented. Link the evidence you use and explain where it stops supporting your interpretation.
You can start with 300–500 words, but this is a suggestion rather than an entry requirement. Use Nexus Historia's scenario creator when you are ready. The aim is to make an argument readers can question, not to claim you have found the one decision that would certainly have won the war.
