Why did the leaders abandoned the Gallipoli campaign?

The leaders abandoned the Gallipoli campaign due to a combination of strategic failures, high casualties, and logistical challenges. The campaign aimed to secure a supply route to Russia and knock the Ottoman Empire out of the war, but it faced fierce resistance and difficult terrain. As the situation deteriorated and with no clear path to victory, military leaders recognized that continuing the campaign would result in further unnecessary losses. Ultimately, the withdrawal in January 1916 was seen as a necessary decision to conserve resources and troops for more viable fronts.
