<span>Gutenberg was instrumental in changing the speed at which the worldcommunicated. Prior to Gutenberg adding several changes together, to wind upwith his version of the 'printing press'. There were several 'ideas' thatpreceded him. The first advance was the use of block letters in a fixed frame,Then came the idea of moving the paper into and out of the press. Finally, wasthe use of a molton metal (Lead-tin Mixture) that allowed for the Type Patternto be recycled for every letter that was needed. The copying by hand , theprevious editions of 'the book', was a laborious process that required manyhands to copy out the text onto linen 'pages', and to make sure that what waswritten ,was accurate. [errors did crop in ocassionally]. Finally the scribeswere very upset when Gutenberg was able to reproduce texts faster than anyscribe was able to set about copying a volume of 100 pages or so(The Boook of.....) So while it would take up to 6 months to finish one copy of a book,Gutenberg was able to produce hundreds in 6-8weeks time.

This enabled more people top read the books of the Bible.</span>

General Robert E. Lee, the Confederate commander of the Army of Northern Virginia, invaded Union territory in an attempt to persuade the United States into a negotiated peace after a hoped-for decisive and damaging attack on Northern soil. It was also believed that a notable Southern victory in Union territory might have resulted in financial support and recognition of the Confederate cause from England or France. General Lee's first invasion of the North, which took place in Maryland during September of 1862, was repulsed by Union forces at the Battle of Antietam, but it was followed by a second invasion by Lee into Pennsylvania during the months of June and July in 1863.
