A 400 yards length of Stormy Trench was attacked by part of a battalion of the 2nd Australian Division late on 1 February, which took the left-hand section and bombed down it to take the rest, before being forced out by a German counter-attack at 4:00 a.m. The Australians attacked again on the night of 4 February, with a battalion and an attached company, with more artillery support and a stock of 12,000 grenades, since the first attack had been defeated when they ran out.
