Researchers just studied 104 letters that were unopened for 265 years. The letters were written to French sailors. Their warship was taken by Britain in 1758. The sailors could not open and read their mail because the letters were taken to London. They gathered dust for two and a half centuries. Many of the letters were love letters.

Researchers studied the letters. They gave a rare look at history. The writers were lovers, parents, sisters and wives. They all had different writing abilities. The letters showed how we live in things like pandemics and wars. The messages were like those people write today. They were about caring for people, and passion.
