Transatlantic telegraph cable

A transatlantic telegraph cable is a cable running under the Atlantic Ocean. It was used for telegraph communications. The first was laid across the bottom of the Atlantic from Ireland to Newfoundland.^[1] The first message was sent on August 16, 1858. It was from Queen Victoria to President James Buchanan.^[2] The cables reduced the communication time between North America and Europe from ten days (by ship) to a matter of minutes. The first cable lasted only three weeks.^[3] Transatlantic telegraph cables have been replaced by transatlantic telecommunications cables.
