The 14th Army began its invasion with a landing on Batan Island (not to be confused with Bataan Peninsula), 120 miles (190 km) off the north coast of Luzon, on 8 December 1941, by selected naval infantry units. Landings on Camiguin Island and at Vigan, Aparri, and Gonzaga in northern Luzon followed two days later.
