During first years of WWI, Rais Ali Delvari and Wassmuss were busy formulating a general Anti-British uprising in Persia. In 12 July 1915, Rais Ali and Tangestani’s attacked the British residency in Bushehr but they were relapsed. Wintle was planning to return and destroy more palm trees, but due to a shortage of ammunition and naval shells and the growing enemy force, along with growing dissent among the local population back in Bushire, it was decided to order the force back to Bushire, considering the destruction of the fort and the village sufficient punishment to the Tangistanis, and the punitive force re-embarked that night.
Bushehr was used as a base by the British Royal Navy in the late 18th century. In the 19th century, Bushehr became an important commercial port. It was occupied by British forces in 1856, during the Anglo-Persian War of 1856–1857. Bushehr surrendered to the British on 9 December 1856. It was occupied again by the British in 1915, the second time due to German intrigue, most notably by Wilhelm Wassmuss and Rais Ali Delvari.In World War I, homeland was neutral.
