On the night of 18th/19th December the Japanese had landed on a broad front stretching from North Point to Shau Kei Wan. They had established a bridgehead. They had moved quickly inland and made for the high ground. They had seized Mount Parker, Mount Butler and Sanatorium Gap during the night. This opened the way for them to enter Guage Basin and the reservoirs at Taitam on the south side of the island. During the following morning Japanese forces had taken Jardines Lookout and were fighting at Wong Nei Chung Gap.
The coastal batteries at Bokhara, D'Aguilar and Cape Collinson and the East Infantry Brigade headquartered at Tai Tam Gap were in danger of being cut off. The Japanese that had landed at Shau Kei Wan were already very close to the Parker and Saiwan Batteries and as a result it became necessary for the East Infantry Brigade under Brigadier Cedric Wallis to withdraw towards Stanley.

The 6 inch Howitzers of the 3rd Medium Battery positioned at Parker and Saiwan Batteries had fired with good effect on Japanese troops on the Mainland. They had also been used for counter battery bombardment and to cover the withdrawal of troops from Devils Peak. Both Brigadier Wallis and Lt Col Cadogan-Rawlinson commanding 5th/7th Rajput Regiment had said how accurate and effective the fire had been from these two medium batteries at Parker and Saiwan.
The two 6-inch How batteries had been ranged on by Japanese artillery but no shell landed nearer than 100 yards from the positions which had been carefully sited at pre-prepared localities with protection provided by the terrain.
The Saiwan Battery did have some near misses from aerial bombing the nearest being 20 yards from one of the gun pits. Alternative positions for the guns had been prepared but were not utilized.
The landing at Sau Kei Wan was very close to the Saiwan Battery and the battery personnel prepared to defend themselves with small arms under 2/Lt Kenneth Allanson who had been transferred from 8th Coast Battery to take charge of the Saiwan Battery. Later that night at around 2100 hours Captain Lucien Feilden had arrived with reinforcements from Parker Battery but later they were forced to withdraw back to Parker Battery. The next day Capt Feilden was killed in action when with other members of the HKSRA he was fighting in an infantry role at Wong Nei Chung Gap.
