By January 1918, the situation for the Ottoman Army in
Palestine had begun to worsen. The new German commander of the Ottoman
Black Sea fleet,
Rebeur Paschwitz, decided to try to relieve Allied naval pressure on Palestine by making a sortie out of the
Dardanelles. Several British naval elements of the
Aegean Squadron had been taking refuge in
Kusu Bay off the islands of Imbros, and they were a prime target for an Ottoman raid. After raiding what shipping could be found at Imbros, Rebeur-Paschwitz planned to proceed to
Mudros and attack the British naval base there. The Allied force guarding the Dardanelles consisted of a few heavy British and French units as well as several monitors tasked with coastal bombardment. Escorting the monitors were several British destroyers. The
pre-dreadnought battleships and were also tasked with guarding the area, but the
Lord Nelson had been tasked with ferrying the squadron's admiral to a conference at
Salonika. Taking advantage of the absence of the British battleship, the Germans and Ottomans decided to dispatch the battlecruiser
Yavûz Sultân Selîm (ex-) and the light cruiser
Midilli (ex-) to attack the area.
Agamemnon was nearby at Mudros, but she was much too slow to chase down the Ottoman ships if they wanted to avoid engaging her.
M28 was a smaller vessel than
Raglan and carried a lighter armament: a single
9.2-inch gun, one 12-pounder, and a
six-pounder anti-aircraft gun. The weak point of both
Raglan and
M28 were their low top speeds of respectively, giving them little capability of escaping an Ottoman raid. In contrast to the British force, the Ottoman vessels were both fast and heavily armed.
Midilli carried eight 150 mm guns, 120
mines, two torpedo tubes, and a top speed of .
Yavûz Sultân Selîm was the most powerful ship in the Ottoman fleet with a top speed of 25.5 knots, ten 283 mm guns, twelve 150 mm guns, a dozen 88 mm guns, and four torpedo tubes. With no heavy units available to repel them, there was little in the means of effective Allied opposition when the Ottomans set out on their mission. ==Battle==
