Sharon played a key role in the War of Attrition. In 1969, he was appointed the Head of IDF's Southern Command. As leader of the southern command, on 29 July Israeli frogmen stormed and destroyed Green Island, a fortress at the northern end of the Gulf of Suez whose radar and antiaircraft installations controlled that sector's airspace. On 9 September Sharon's forces carried out Operation Raviv, a large-scale raid along the western shore of the Gulf of Suez. Landing craft ferried across Russian-made tanks and armored personnel carriers that Israel had captured in 1967, and the small column harried the Egyptians for ten hours.
