World War I was the first large-scale global war of hot weapons after human bid farewell to cold weapons, which opened a new era of human war.

The Battle of the Somme, which started in July 19 16 and ended in July 10/1,was one of the most difficult and costly battles in the First World War.

On the first day of the battle alone, the British army suffered more than 57,000 casualties, including more than19,000 soldiers killed, making it the worst day in the country's military history. Nearly five months after the Battle of the Somme, there were more than 3 million combatants on both sides, and the number of casualties exceeded 1 10,000.

The following pictures are extremely bloody. I hope friends with limited psychological endurance don't look down.

The First World War happened shortly after the demise of the Qing Dynasty in China. The once powerful Great Qing Dynasty was conquered by the advanced western hot weapons at that time, and the century-old national humiliation was precisely because our science and technology were backward.

War is cruel, peace is precious, and now our life is hard-won. With the development of science, war is getting farther and farther away from mankind. In the nuclear age, no one can afford another world war.
