During the night of 21/22 September 42nd (EL) Division went back into the line, east of Havrincourt Wood, to prepare for an assault on the Hindenburg Line. The Signal Company put back into use a buried cable it had laid a year earlier. In two continuous days of fighting (the Battle of the Canal du Nord, 27–28 September) the East Lancashires leap-frogged through five successive objectives, with the sappers clearing the Hindenburg Line dugouts of booby-traps.
