Known as one of the bloodiest battles in Britain's military history, there is a lot to learn about what actually happened during the Battle of the Somme.
But here are some key points to get you started...
The 141-day offensive cost thousands of lives, with over a million men killed or wounded from both sides by the time it reached its end.
The British Army suffered almost 60,000 casualties on just the first day - July 1, 1916 - as they attempted to break through German lines in France.
By the time the battle reached its end in November 1916, the Allied Forces had advanced 60 miles along a 20-mile strip of land.
