Cable Timeline: 1845-1900 by Bill Glover

Click on the Route links to see cable samples, the Company or Operator links for full descriptions, the ship name links to see descriptions or images. Atlantic cables and their connecting systems are highlighted in green. John Seymour links in the Timeline between 1875 and 1897 are to the descriptions of those voyages in Dougal Watson's extensive section on his ancestor's life at sea. Please note that Timeline entries within each year are not necessarily chronological, as the exact date of laying is generally not known.
Year	Route	Manufacturer	Company or Operator	Cable Ships	Notes
1845	Laid between HMS Blake and HMS Pique in Portsmouth Harbour	S.W. Silver & Co	S.W. Silver & Co	HMS Blake - HMS Pique	Charles West of S.W. Silver & Company manufactured one mile of cable insulated with rubber and carried out tests on it in Portsmouth Harbour. He subsequently obtained permission from HM Government to lay a cable across the English Channel, but was unable to raise the necessary capital so the idea was dropped.
1850	Dover, England - Calais, France	Gutta Percha Co 25 nm	Submarine Telegraph Co	Goliath - HMS Widgeon	System 25 nm. CABLE: 1 copper wire No 16 BWG covered with gutta percha to No 2 BWG. 8 or 16lb lead weights were attached to the cable as it was laid to help it sink,. Cable was cut by French fisherman after three days
1851	Dover, England - Calais, France (St Margarets Bay - Sangatte No 1)	Gutta Percha Co supplied the core. - R.S. Newall & Co - Wilkins & Wetherly	Submarine Telegraph Co	HMS Blazer (1) - HMS Fearless - Red Rover (1)	System 25½ nm. CABLE: 4 copper wires No 16 BWG each covered with gutta percha to No 2 BWG, then formed into a cable. The spaces were packed with tarred yarn and a further layer of gutta percha was added. Tarred hemp was wrapped around the core then it was armoured with 10 No 1 BWG iron wires. Cable ran out before reaching France. A temporary repair was made. Red Rover laid replacement a month later. Taken over by the GPO in 1890. Wilkins & Wetherley were awarded the contract to add the armouring, but in doing so they infringed Newall's patent and so the bulk of the work was carried out by Newall's
