History of Metallurgy

In 1709 Abraham Darby, an ironmaster with a furnace at Coalbrookdale on the river Severn, discovers that coke can be used instead of charcoal for the smelting of pig iron (used for cast-iron products). This Severn region becomes Britain's centre of iron production in the early stages of the Industrial Revolution.

Lee's greatest victories were the Seven Days Battles, the Second Battle of Bull Run, the Battle of Fredericksburg and the Battle of Chancellorsville, but both of his campaigns to invade the North ended in failure. Barely escaping defeat at the Battle of Antietam in 1862, Lee was forced to return to the South. In early July 1863, Lee was decisively defeated at the Battle of Gettysburg in Pennsylvania. However, due to ineffectual pursuit by the commander of Union forces, ...
