There, they connected two ends of a 4,000 kilometer long, 1.5 centimeter wide cable, linking for the first time the European and North American continents by telegraph.

Just over two weeks later, the UK's Queen Victoria sent a congratulatory message to then US President James Buchanan, which was followed by a parade through the streets of New York, featuring a replica of a ship which helped lay the cable and fireworks over City Hall.
