While escorting Gibraltar-Bizerta convoy, on May 11, 1918, an enemy submarine, which was not seen, torpedoed the French steamship _Susette Fraisenette_ at 3:39 a. m. With excellent judgment he assumed that submarine had dived under the convoy, and in following out the theory sighted the submarine on the surface at daylight, compelling it to submerge. This submarine was subsequently sunk in the Adriatic, and the survivors testified that the attack of the _Venetia_ on this occasion drove them off, and saved the convoy from further attack. Commended in British Senior Naval Officer's letter 78-14 of 24th May, 1918, and British Commander-Chief's Mediterranean letter No. 2089-93 of 23 June, 1918. While escort to Gibraltar-Bizerta convoy on May 17, 1918, the British steamship _Sculptor_ was torpedoed at 6:48 p. m. Submarine was not seen, but the _Venetia_, having been previously detailed to attack with depth-charges, and remain behind four hours to keep down submarine, did so. At 7:02 p. m. wake of submarine was sighted and depth-charges dropped. On May 18th an enemy submarine interned at Cartagena, Spain, and was officially assumed to have been damaged by the _Venetia_. While on escort duty, Gibraltar-Genoa, the British steamship _Messidor_ was torpedoed at 7:24 p. m., July 23, 1918, and the _Venetia_ instantly made attack, dropping thirteen depth-charges on pre-arranged plan. The cruiser _Chester_ had two encounters with submarines. While on convoy duty November 9, 1917, it attacked with gunfire a submarine which had sunk one of the vessels of the convoy, compelling the U-boat to submerge. On September 5, 1918, at 1:04 a. m., the _Chester_, on ocean escort, sighted a submarine close aboard on the starboard bow. First the cruiser attempted to ram the enemy, then attacked the undersea craft with depth-charges, which apparently damaged the U-boat. Four days later a submarine attacked Convoy GGA-54, torpedoing and sinking the British steamship _Arabis_. The _Paducah_ attacked with depth-bombs and, according to reports, damaged the submarine. The _Seneca_ on September 16th drove off a submarine which attacked Convoy OM-99. The _U. S. S. Druid_ and _H. M. S. Gilia_ repulsed an attack on Convoy BG-65, on September 22nd. Escorting Convoy BG-67, on September 30th, the _Seneca_ sighted a periscope and attacked with depth-charges and gunfire.
