Landing at Suvla Bay happened on 1915-08-15.

The French (at Cannakkale across the Dardanelles. They withdrew quickly though, as the French often do) and the British at Suvla Bay and Cape Helles.

It depends what you deem a battle. At Anzac there was the landings then the August Offensive. Battles like Lone Pine, the Nek and Chunuk Bair occured here. At Suvla Bay and Cape Helles there were more like the three battles of Krithia.

There were several landing places. The Anzacs landed at a place that soon became known as Anzac Cove. The British landed at Cape Helles and Suvla Bay. The French landed in the Cannakale province across the Dardenelles but later withdrew.

The Battle of Lone Pine, along with the Battle of Sari Bair, was planned by Allied regional Commander-in-Chief Sir Ian Hamilton as an operation that was meant to shift focus away from the planned Allied landings at Suvla Bay on 6 August 1915.
