officer was killed by shell-fire and Galileo Galilei was captured along with many documents including operational orders for four other Italian submarines. Archimede, Perla and Guglielmotti sailed from 19 to 21 June. On 26 June, Guglielmotti ran onto a shoal and suffered severe damage; the wreck was salvaged later. Documents recovered from Galileo Galilei were used to intercept and damage Torricelli on 21 June. The submarine headed for home but was caught off Perim Island and sunk by Kandahar, Kingston, Khartoum and the sloop . Several hours afterwards, a torpedo on Khartoum, damaged by a shell from Torricelli, exploded and caused an uncontrollable fire. Khartoum tried to reach Perim Harbour about distant but the crew and prisoners had to abandon ship; later a magazine explosion wrecked the vessel. The sloop Falmouth exploited the document find from Galileo Galilei to sink Galvani in the Gulf of Oman on 24 June. On 13 August, Galileo Ferraris made an abortive attempt to intercept the battleship en route from Suez to Aden. From 13 to 19 August Kimberley and the sloop bombarded Italian troops advancing west of Berbera in British Somaliland. Italian air raids on Berbera caused splinter damage to Hobart as it participated in the evacuation of Berbera with Carlisle, Ceres, Kandahar, Kimberley and the sloops Shoreham, , Auckland, auxiliary cruisers Chakdina, Chantala and Laomédon, the transport and the hospital ship , lifting 5,960 troops, 1,266 civilians and 184 sick and wounded. On 18 November the cruiser bombarded Zante in Italian Somaliland British naval forces supported land operations and blockaded the remnants the Red Sea Flotilla at Massawa. By the end of 1940, the British had gained control of East African coastal routes and the Red Sea; Italian forces in the AOI declined as fuel, spare parts and supplies from Italy ran out. There were six Italian air attacks on convoys in October and none after 4 November. Red Sea convoys During 16 June 1940, Galileo Galilei sank the Norwegian tanker James Stove (8,215 Gross register tonnage [GRT]), sailing independently about south of Aden. On 2 July the first of the BN convoys (Bombay Northward; Bombay to Suez, then Aden to Suez 1940–1941), comprising six tankers and three freighters, assembled in the Gulf of Aden. Italian sorties against the BN–BS convoys (Bombay Southward; Suez to Aden, late 1940 to early 1941) were dispiriting failures; from 26 to 31 July, Guglielmotti failed to find
