There was then another rest until the Battle of St Quentin Canal began on 29 September. Facing the most formidable part of the Hindenburg Line on the St Quentin Canal, 5th/6th RS did not go into action until 1 October, once the line had been breached. At 16.00 they were directed against the key position in the German second line, the village of Sequehart, just north of St Quentin. The village changed hands four times until on 3 October the battalion, which had specifically asked for another chance to take the village, succeeded in holding it, despite heavy shelling and two more counter-attacks.
