The main operation started on 6 August with a fresh landing 5 miles (8.0 km) north of Anzac at Suvla Bay in conjunction with the Australian and New Zealand Army Corps. The Allies mounted an attack north into the rugged country alongside the Sari Bair range with the aim of capturing the high ground and linking with the Suvla landing. At Helles, the British and French were now to remain largely on the defensive.
