Quite right too!

From a bagpipe history site:

"As a musical instrument of war, the Great Pipes of the Highlands were without equal, according to historians. The shrill and penetrating notes worked well in the roar and din of battle and pipes could be heard at distances up to 10 miles. Because of the importance of the bagpipes to any Highland army, they were classified as an instrument of war by the Loyalist government during the Highland uprising in the 1700s. After the defeat of Bonnie Prince Charlie in 1745, kilts and bagpipes were outlawed, the pipes being classified as instruments of war."
