Attack by Dayaks
To keep up morale following Amherst's departure, Maxwell began organising his remaining 200 men (and one woman) to secure their position and gather supplies. The men were divided into parties, with one ordered to dig a well while another returned to the wreck of Alceste to salvage what weapons and equipment they could. A third party was ordered to clear a path to the island's central hill, where a cool cave could be used as a larder and trees felled to form a protective stockade. By the end of the first day the well was producing a steady supply of water.
The party aboard Alceste, having determined that the ship was in no immediate danger of sinking, decided to remain aboard overnight. However, at dawn they awoke to discover the ship surrounded by Dayak (or Malay) proas armed with swivel guns. The party escaped on the raft, only reaching the island ahead of the pursuing proas with the assistance of boats sent to meet them carrying armed Royal Marines. With the wreck vacated, the Dayaks began enthusiastically looting it and several proas approached the island, landing their crews on offshore rocks to both observe the British and store their salvage. Maxwell hastily organised defensive positions in case the Dayaks attacked the island, completing the stockade on the island's hill and preparing sharpened stakes and hundreds of improvised cartridges for the group's 30 muskets. Over the next few days the proas approached the island several times, but despite attempts by the British to communicate with them, never landed. Eventually, on 22 February, Maxwell took advantage of the divided Dayak positions to drive their observers off the rocks, with the intention of recapturing the wreck. This was initially successful, but the departing Dayaks set fire to Alceste, burning her to the waterline. The destruction of the frigate's upper works exposed her hold, and the next morning the stranded sailors were able to collect some supplies that had floated out.
During the early morning of 26 February, British sentries spotted two proas attempting to land at the cove where the remaining British boats were anchored. Taking one of the boats to intercept the proas, Lieutenant Hay boarded a Dayak canoe and captured it, despite fire from the Dayak guns. Four Dayaks were killed, two captured, and five jumped into the sea and drowned themselves, having scuttled their proa. Later in the day fourteen more proas appeared, led by a large vessel carrying a rajah. These approached the island and several Malays came ashore, a number of British sailors being admitted on board the rajah's canoe in return. The inability of either side to speak the others language hindered negotiations, and the Malays retreated to their boats late in the day. The rajah subsequently directed renewed salvage operations on the wreck, seeking especially the copper nails that had held the ship's beams together. By 2 March there were nearly 30 proas off the island, 20 of which were detached to open an ineffective long-range fire on the British positions ashore, accompanied by frenzied drumming and the bashing of gongs. Although further attempts were made to communicate with the proas, and messages successfully passed to them in the hope someone in authority would transmit them to nearby settlements, the British crew expected an attack at any moment. In preparation, Maxwell gathered his men together and spoke to them:
My lads, you must all have observed the great increase in the enemy's force, and the threatening posture they have assumed. I have reason to believe they will attack us this night. I do not wish to conceal our real state, because I do not believe there is a man here who is afraid to face any sort of danger. We are in a position to defend ourselves against regular troops, far less a set of naked savages, with their spears and krisses. It is true they have swivels in their boats, but they cannot act here. I have not observed that they have any muskets, but if they have, so have we. When we were first thrown on shore we could only muster seventy-five musket ball cartridges—we now have sixteen hundred. They cannot send up, I believe, more than five hundred men; but with two hundred such as now stand around me, I do not fear a thousand—nor fifteen hundred of them. The pikemen standing firm, we will give them such a volley of musketry as they will be little prepared for; and when they are thrown into confusion, we will sally out, chase them into the water, and ten to one but we secure their vessels. let every man be on the alert, and should these barbarians this night attempt our hill, I trust we shall convince them they are dealing with Britons.
So loud was the cheering that followed this address that the proas fell silent, the Dayaks apparently unnerved. In the morning however the 20 canoes were still offshore and, with the anticipated rescue overdue and supplies running low, a desperate plan was made to use the ship's boats to board and capture enough Dayak vessels to enable the entire crew to reach Batavia. However, while these plans were being formed the British East India Company's (EIC) armed brig Ternate appeared on the southern horizon.
