Lingayen Gulf operations scheduled for early 1945 demanded the presence of all available tender strength at Ulithi in the Caroline Islands. Early in January "Piedmont" stood out of Manus Island for Ulithi with Service Squadron 10. January through April saw "Piedmont" in his most sustained effort. Those same months which witnessed the seaborne invasions of Lingayen, Iwo Jima, and Okinawa, found the repair department averaging more than 1,000 completed job orders and almost 100,000-man hours of work each month.
