In July 1916, Britain led an Allied offensive against German positions on the Western Front near the Somme river in France. The British army suffered 60,000 casualties on the first day. By the end of the battle in November, one million men had been killed or wounded. The Somme became synonymous with the horrors of war.

We hear BBC archive recordings of veterans who fought in one of the bloodiest battles in history.

This programme, first broadcast in 2016, was presented by Alex Last.

Eye-witness accounts brought to life by archive. Witness History is for those fascinated by and curious about the past. We take you to the events that have shaped our world through the eyes of the people who were there.

For nine minutes every day, we take you back in time and all over the world, to examine wars, coups, scientific discoveries, cultural moments and much more.

Recent episodes explore everything from how the Excel spreadsheet was developed, the creation of cartoon rabbit Miffy and how the sound barrier was broken.

We look at the lives of some of the most famous leaders, artists, scientists and personalities in history, including: the moment Reagan and Gorbachev met in Geneva, Haitian singer Emerante de Pradines’ life and Omar Sharif’s legendary movie entrance in Lawrence of Arabia.

You can learn all about fascinating and surprising stories, like the invention of a stent which has saved lives around the world; the birth of the G7; and the meeting of Maldives’ ministers underwater. We cover everything from World War Two and Cold War stories to Black History Month and our journeys into space.

In 1981, Australia launched a fight against skin cancer with help from a yellow cartoon seagull and a catchy jingle.

The Slip Slop Slap campaign was created by an advertising team of Phillip Adams, Peter Best and Alex Stitt. The three men gave their services for free to help the Cancer Council Victoria charity spread the message.

Soon, Australians began to slip on a shirt, slop on sunscreen and slap on a hat in response to a warning by Sid the seagull.

Today, the campaign is widely credited in helping change attitudes to sun protection. Professor David Hill, former head of the charity, talks to Jane Wilkinson about how it happened.

In June 2016, voters in the UK were asked whether they wanted to remain in the European Union or leave. It was a decision that would divide the country and reshape relations with its closest neighbours.

As the result emerged overnight, Rory Montgomery was one of the officials responsible for preparing Ireland's response.

The former diplomat remembers watching the night unfold from Dublin and tells Helen Ledwick why it mattered so much for Ireland.
