Stigweard, Quite a few years ago the BBC did a series on the British Empire, for the India episode they had John Cameron the Scottish journalist write and narrate his account of the Raj and their doings in that part of the world.
He referred to an incident in Afghanistan in which a large number of British troops were wiped out by the Afghans, John found after much research that this episode of the Afghan campaign in the [circa] 1850s was never seen in any history books.    In my time in England I was amazed to find that very little was known of Englands affairs with her neighbouring island,in a recent University Challenge TV Programme, three simple questions on Irish geography went unanswered by the students.

Nothing seems to have changed when we are confronted by some of the opinions on Ireland by various British `catters.
