The Battle of the Boyne took place on July 1, not July 12. You're obviously not about to take my advice to consult books or the BBC History website to (at least) attain some accuracy with your beloved anniversary. The link you posted is to a garbage website.

Nevertheless, the one date you're addicted to thinking particularly significant (and remember, it's July 1, ok?) is still some weeks away. Don't be such a one-trick-pony! If only you took the trouble to learn (and fulfill what you promise by writing dates, in the plural) between today and July 1 there are other "Britannic" calendar points that should warm the cockles of your fascist heart, such as...

Today, June 11 - 1987: Prime Minister Margaret Thatcher wins an historic third term, the first politician to do so in 160 years.

June 12 - 1701: The Act of Settlement ensures a Protestant succession in England by passing the throne to Hanover.

And how could I fail to remind you of your OTHER obsession...

June 18 - 1815: Wellington decisively defeats Napoleon at the Battle of Waterloo.

Perhaps you should also think of inaugurating a GALLIA thread in order to dump it there. Over and over.
