It is a question often asked: what was the worst day in Britain’s military history?
Depending perhaps on their definition of ‘Britain’, some might point to 14 October 1066, when a Norman victory at the Battle of Hastings set these isles on a new course. Others might claim it was 29 March 1461, during the Wars of the Roses, when an estimated 50,000 soldiers clashed at Towton, the largest and bloodiest battle fought on home soil. For his part, no less a figure than Winston Churchill was certain, when he described the WWII Fall of Singapore on 15 February 1942 as truly the ‘greatest disaster’ ever to befall the British Army.
While these may all be worthy contenders for the ignominious title of Britain’s worst military debacle, it is another date – one that fell 110 years ago this summer – that for many will spring most readily to mind. When it comes to the grim business of wholesale slaughter and the futile waste of young British lives, 1 July 1916 – the first day of the Battle of the Somme – rightly holds a unique place in the national consciousness.
British losses on that date numbered a staggering 57,470, including those ‘missing’, with 19,240 killed in action – making it the bloodiest single day in the Army’s history. Among those laying down their lives on that summer’s day were the young volunteers of Lord Kitchener’s inexperienced ‘New Army’, whole battalions of which were destroyed within hours of seeing action for the first time.
The battle would continue along a 25-mile front until 18 November – four months during which the flower of the nation’s youth would be held firmly to the butcher’s block. By the time the fighting was finished, Britain had suffered some 420,000 casualties, and the French around 204,000, while German losses may have reached 670,000 according to one estimate (the number is contested): a total of more than a million mostly young men, and all for little or no strategic gain.
In the first part of our special feature for this issue, MHM tells the story of a titanic struggle that for many sums up the horror of 20th-century warfare. In the second part, we look in more detail at the Battle of the Boar’s Head, the lesser known clash of arms that immediately preceded the Somme, whose appalling casualty rate laid down a marker for the carnage to come.
This is an extract from a special feature on the Somme from the June/ July 2026 issue of Military History Matters magazine.
