"While the Irish were banned from many employment opportunities at the time, they did not grow discouraged. With a fervor possessed of many immigrants, they labored their way into the mainstream of America.

They joined the armies of America during the Civil War. Entire regiments were made up of Irish descendants and immigrants, and the bagpipes and drums were again brought to the fore to lead men into battle."

This site of the National Law Enforcements Officers' Memorial Fund does not offer chapter and verse, but it cites

www.west-point.org/taps/Taps.html apparently a West Point site. The NLEOMF also provides a history of bagpipes. It is very interesting. This Scotch-Irishman learned something. Stan
