Input: Question: In which of the World War II campaigns that the North Irish Horse participated in did they have the most victories? Passage:The North Irish Horse is a yeomanry unit of the British Territorial Army raised in the northern counties of Ireland in the aftermath of the Second Boer War. Raised and patronized by the nobility from its inception to the present day, it was one of the first non-regular units to be deployed to France and the Low Counties with the British Expeditionary Force in 1914 during World War I and fought with distinction both as mounted troops and later as a Cyclist Regiment, achieving 18 battle honours. The regiment was reduced to a single man in the inter war years and re-raised for World War II, when it achieved its greatest distinctions in the North African and Italian campaigns. Reduced again after the Cold War, the regiment's name still exists in B (North Irish Horse) Squadron, the Scottish and North Irish Yeomanry and 40 (North Irish Horse) Signal Squadron, part of 32 Signal Regiment.
