What were they trying to achieve in World War 1 Gallipoli?

In World War I, the Gallipoli Campaign aimed to secure a sea route to Russia and open a new front against the Central Powers. The Allies sought to capture the Dardanelles Strait, ultimately leading to the capture of Constantinople (now Istanbul) and weakening Ottoman control. By doing so, they hoped to boost morale among their troops and support their Russian allies, while also potentially encouraging other nations to join the war effort. However, the campaign resulted in heavy casualties and ultimately failed to achieve its objectives.
