island overlooking the Belgrade, while Austria got the other part, in the direction of Zemun and Banat. In liberating Belgrade in 1806 the rebel army headed by Karađorđe also used the island for military purposes, as the Serbian artillery with 500 soldiers was bombing the Kalemegdan fortress from there. Under the command of and Vuk Ilić, Serbian artillery was out of Ottoman reach and left undisturbed cannonading the Lower Town of the fortress. Turkish city plan from 1863 still used the name Babalık for the island. During the offensive in 1915 by Austria-Hungary against Belgrade, Austria-Hungary forces used the island to launch their attacks. After the World War I, island became part of the new Yugoslav state. After 1918, a small colony of 20 destitute inhabitants of Zemun built stilt houses on the island which was then colloquially called "Sirotinjska Ada" (Poor man's Island). In this period the entire area of the island was cultivated, mostly corn and watermelons. On the lower tip of the island, a beach was arranged and named Dorćol Beach or Lapat Beach.

The project was planned to connect Zemun to Kalemegdan on Belgrade Fortress, via Great War Island. The interval of the cabins was set at 2 minutes and the entire route was supposed to last 5 minutes.

When construction of New Belgrade began in 1948, the city government made a decision to completely destroy the island by using its sand and earth to cover the marshes of Syrmia, where new city was to be built. However, the deposits of alluvial materials continually brought onto the island from the Danube completely prevented this from happening.
