With its strategically important location on the banks of the River Ribble, Preston is no stranger to wars and warfare. Conquering Roman legions passed this way, Robert the Bruce made devastating raids here, militia troops were recruited for Queen Mary, Cavaliers and Roundheads crossed swords, and the Riot Act was read at Preston, leading to bloodshed and bitterness. The barracks on Fulwood Moor became a place for legendary regiments and battalions to prepare for war. Heroes of the Crimea, the Boer War, international conflicts and both world wars emerged from Preston. Weapons for worldwide warfare have been produced here too - be they tanks or trucks, bombs or jet fighters - and industry has developed accordingly. Ships laden with sailors, troops and precious cargo have docked here, and the city's railway station has bade farewell to many soldiers and sailors en route to war. Local author Keith Johnson shows that Preston's proud military heritage lives on through its historic sites, personalities, monuments and memorials.
