the Australians was not seen as a prelude to attack—Malaya Command believed that it would last several days and would later switch its focus to the north-east, despite its ferocity exceeding anything the Allies had experienced thus far in the campaign; no order was passed to the Commonwealth artillery units to bombard possible Japanese assembly areas. Shortly before 20:30 on 8 February, the first wave of Japanese troops from the 5th Division and 18th Division began crossing the Johor Strait. The main weight of the Japanese force, about 13,000 men, from 16 assault battalions, with five in reserve, attacked the 22nd Australian Brigade. The assault was received by the 2/18th Battalion and the 2/20th Battalion. Each Japanese division had 150 barges and collapsible boats, sufficient for lifts of 4,000. During the first night 13,000 Japanese troops landed and were followed by another 10,000 after first light. The Australians numbered just 3,000 men and lacked any significant reserve. As the landing craft closed on the Australian positions, machine gunners from the 2/4th Machine Gun Battalion, interspersed amongst the rifle companies, opened fire. Spotlights had been placed on the beaches by a British unit to illuminate an invasion force on the water but many had been damaged by the bombardment and no order was made to turn the others on. The initial wave was concentrated against the positions occupied by the 2/18th and 2/20th Battalions, around the Buloh River, as well as one company from the 2/19th Battalion. Over the course of an hour, intense fighting took place on the right flank of the 2/19th Battalion, until its positions were overrun, the Japanese then advanced inland concealed by the darkness and the vegetation. The resistance put up by the company from the 2/19th pushed the follow-on waves of Japanese craft to land around the mouth of Murai River, which resulted in them creating a gap between the 2/19th and 2/18th battalions. From there the Japanese launched two concerted attacks against the 2/18th, which were met with massed fire before they overwhelmed the Australians by weight of numbers. Urgent requests for fire support were made and throughout the night the 2/15th Field Regiment fired over 4,800 rounds. Fierce fighting raged throughout the evening but due to the terrain and the darkness, the Japanese were able to disperse into the undergrowth, surround and overwhelm pockets of Australian resistance or bypass them exploiting gaps in
