This Day In History: 1917-10-09

66th Division, a 2nd-line Lancashire TA formation which includes 2/4th and 2/5th East Lancashires, attack the Passchendaele Ridge at dawn after a nightmare eleven hour approach march. They flounder a few hundred yards into the morass of the aptly-named Waterfields at the cost of almost seven hundred casualties, and in appalling conditions hold their gains against repeated counter-attacks.
