The battle was fought on 1 July 1690 at a fordable river bend four miles west of Drogheda. The main body of Williamite infantry was concentrated on fording the river at the village of Oldbridge, which was approached by a deep and sheltenng glen. First, however, a detachment of cavalry and infantry made a flanking attack upstream, which forced James to divert troops to prevent his retreat being cut off. William's army was stronger by at least 10,000 men, but after these troops were drawn off he had three-to-one superiority in the main arena. By mid-afternoon the Jacobite army was in retreat, outpaced by James himself, who rode to Dublin to warn the city of William's approach. He was in France before the month was out. On 6 July William entered Dublin, where he gave thanks for victory in Christ Church Cathedral. The Battle of the Boyne is recalled each July in the celebrations of the Orange Order, not on the first day but on "the Twelfth", for eleven days were lost with the change from the Julian to the Gregorian calendar in 1752. http://www.irelandseye.com/aarticles/history/events/dates/ch5.sh http://en.wikipedia.org/wiki/Battle_of_the_Boyne Mar 17 09, 7:45 AM
