In the Philippines... On land, the US 1st Cavalry Division continues advancing on the northeast coast of Leyte. Other elements of US 10th and US 24th Corps, to the south, are inactive because of a lack of supplies. At sea, the Japanese Southern Force (Nishimura) and the 2nd Striking Force (Shima) engage American forces, commanded by Admiral Oldendorf, blocking the Surigao Strait. After suffering losses the Japanese withdraw. The Center Force (Kurita) passes through the San Bernardino Strait and engages US Task Force 77.4.3 (Sprague) which is then reinforced by aircraft from TF77.4.2 as it attempts to retreat. Center Force suffers some losses and Admiral Kurita chooses to withdraw because he believes the aircraft are from US Task Force 38. While Center Force turns back, TF77.4.3 is struck by Kamikaze strikes which sink 4 escort carriers. These are the first significant Kamikaze attacks recorded. At the same time, TF77.4.1 is also attacked by Kamikazes. Meanwhile, the Northern Force (Ozawa) is attacked TF38. Only the carrier-battleships (Ise and Hyuga) survive the day. During the engagement, two groups of TF38 turn back to attack Center Force but fail to arrive in time.
