Predictions for Experience of Warfare:
Crimean War: Impact of war reporting - Fenton and Russell (probably not going to be anything to do with the Charge of the Light Brigade, as it's been done in various forms already)
Second Boer War: Concentration Camps and Guerrilla Warfare or Army and Social Reform
Western Front: Harder to gauge because there has been quite an even spread of topics, but I'd say Discipline in the Army (controversy with how strict it was) or BEF in 1918/German defeat (why the British were formidable).
Home Front: DORA or recruitment for the Army
