to defend the territory against a hypothetical Japanese invasion. However, this refusal left the Allied flank severely exposed, and a 400-man combined Dutch-Australian force subsequently occupied Portuguese Timor on 17 December. In response, the
Portuguese Prime Minister,
Salazar, protested to the Allied governments, while the governor of Portuguese Timor declared himself a prisoner in order to preserve the appearance of neutrality. Most of the Dutch troops and the whole of the 2/2nd Independent Company were subsequently transferred to Portuguese Timor and distributed in small detachments around the territory.
Neutral Portuguese Timor had not been originally included among the Japanese war objectives, but after Allied occupation violated its neutrality the Japanese decided to invade.
The Portuguese and the British governments reached an agreement that established the withdrawal of the Allied forces from Portuguese Timor, in exchange for the sending, by Portugal, of a military force to replace them. On 28 January 1942, the Portuguese force sailed from

Imperial Japanese Army
The Imperial Japanese Army (IJA; , ''Dai-Nippon Teikoku Rikugun'', "Army of the Greater Japanese Empire") was the principal ground force of the Empire of Japan from 1871 to 1945. It played a central role in Japan’s rapid modernization during th ...
's 228th Regimental Group,
38th Division,
XVI Army, under the command of Colonel
Sadashichi Doi, began landing in Dili. Initially, the Japanese ships were mistaken for vessels carrying the foreseen Portuguese reinforcements, and the Allies were caught by surprise. Nevertheless, they were well-prepared, and the garrison began an orderly withdrawal, covered by the 18-strong Australian Commando No. 2 Section stationed at the airfield. According to Australian accounts, the commandos killed an estimated 200 Japanese in the first hours of the battle; the Japanese army recorded its casualties as only seven men, but native accounts of the landings support the Australian claims.
Another group of Australian commandos, No. 7 Section, was less fortunate, driving into a Japanese roadblock by chance. Despite surrendering, according to military historian Brad Manera all but one were massacred by the Japanese.
Outnumbered, the surviving Australians withdrew to the south and to the east, into the mountainous interior. Van Straten and 200 Dutch East Indies troops headed southwest toward the border.
Japanese landings in Dutch Timor, 19–20 February 1942
On the same night, Allied forces in Dutch Timor also came under extremely intense air attacks, which had already caused the small RAAF force to be withdrawn to Australia. The bombing was followed up by the landing of the main body of the 228th Regimental Group—two battalions totalling around 4,000 men—on the undefended southwest side of the island, at the Paha River. Five
Type 94 tankettes were landed to support the Japanese infantry, and the force advanced north, cutting off the Dutch positions in the west and attacking the 2/40th Battalion positions at Penfui. A Japanese company thrust north-east to

, aiming to cut off the Allied retreat. In response, Sparrow Force HQ was immediately moved further east, towards Champlong.
Leggatt ordered the destruction of the airfield, but the Allied line of retreat towards Champlong had been cut off by the dropping of about 300 Japanese marine paratroopers, from the 3rd Yokosuka
Special Naval Landing Force, near Usua, east of Kupang.
The Japanese paratroopers occupied Usau and set up defence positions on a nearby hill that overlooks the main road leading to Usau. Sparrow Force HQ moved further eastward, and Leggatt's men launched a sustained and devastating assault on the paratroopers, culminating in a bayonet charge, which managed to quickly overrun the Japanese positions. By the morning of 23 February, the 2/40th Battalion had killed all but a couple of the Japanese paratroopers who had fled into the thick jungle. Sparrow force continued on their retreat to Champlong, but later that morning, the rear of the convoy was assaulted by Japanese tankettes. This assault momentarily halted when a couple of Japanese bombers tried to bomb the convoy, but had accidentally bombed the tankettes, destroying 3 tankettes. During the afternoon, they were surrounded by a battalion of Japanese soldiers that had encircled their force.With his soldiers running low on ammunition, exhausted, and carrying many men with serious wounds, Leggatt accepted a Japanese invitation to surrender at Usua. The 2/40th Battalion had suffered 84 killed and 132 wounded in the fighting, while more than twice that number would die as

Veale and the Sparrow Force HQ force—including about 290 Australian and Dutch troops—continued eastward across the border, to link up with the 2/2 Independent Company.
Australian commandos continue to resist, February – August 1942

By the end of February, the Japanese controlled most of Dutch Timor and the area around Dili in the northeast. However, the Australians remained in the south and east of the island. The 2/2nd Independent Company was specially trained for commando-style, stay behind operations and it had its own engineers and signallers, although it lacked heavy weapons and vehicles.
The commandos were hidden throughout the mountains of Portuguese Timor, and they commenced raids against the Japanese, assisted by Timorese guides, native carriers and mountain ponies.
In relatively small operations such as these, military
folboats (collapsible kayaks, or folding boats) were deployed for use by Sparrow Force and the Independent Companies, as they could then better penetrate the dense coastal vegetation for surveillance, raids and rescue with minimum profile exposed to the enemy. This was the first ever use of folboats in Southeast Asia for wartime operations, being Australian built Hohn 'Kayak' type.
Although Portuguese officials—under Governor
Manuel Ferreira de Carvalho—remained officially neutral and in charge of civil affairs, both the European Portuguese and the indigenous East Timorese were usually sympathetic to the Allies, who were able to use the local telephone system to communicate among themselves and to gather intelligence on Japanese movements. However, the Allies initially did not have functioning radio equipment and were unable to contact Australia to inform them of their continued resistance.

Japanese counter-offensive, August 1942
In August, the
Japanese 48th Division—commanded by Lieutenant General
Yuitsu Tsuchihashi—began arriving from the Philippines and garrisoned Kupang, Dili and Malacca, relieving the Ito detachment. Tsuchihashi then launched a major counter-offensive in an attempt to push the Australians into a corner on the south coast of the island.

on the northeast coast. Another moved eastward from Dutch Timor to attack Dutch positions in the central south of the island. The offensive ended on 19 August when the main Japanese force was withdrawn to Rabaul, but not before they secured the central town of
Maubisse and the southern port of Beco. The Japanese were also recruiting significant numbers of Timorese civilians, who provided intelligence on Allied movements.
Meanwhile, also in late-August, a parallel conflict began when the Maubisse rebelled against the Portuguese.
During September the main body of the Japanese 48th Division began arriving to take over the campaign. The Australians also sent reinforcements, in the form of the 450-strong 2/4th Independent Company—known as "Lancer Force"—which arrived on 23 September. The destroyer ran aground at the southern port of
Betano while landing the 2/4th, and had to be abandoned after it came under air attack. The ship's crew was safely evacuated by and on 25 September 1942 and the ship destroyed by demolition charges. On 27 September, the Japanese mounted a thrust from Dili towards the wreck of ''Voyager'', but without any significant success.
By October, the Japanese had succeeded in recruiting significant numbers of Timorese civilians, who suffered severe casualties when used in frontal assaults against the Allies. These collaborative civilians were widely called as
Colunas Negras''
' by the Portuguese. The Portuguese were also being pressured to assist the Japanese, and at least 26 Portuguese civilians were killed in the first six months of the occupation, including local officials and a Catholic priest. On 1 November, the Allied high command approved the issuing of weapons to Portuguese officials, a policy which had previously been carried out on an informal basis. At around the same time, the Japanese ordered all Portuguese civilians to move to a "neutral zone" by 15 November. Those who failed to comply were to be considered accomplices of the Allies. This succeeded only in encouraging the Portuguese to cooperate with the Allies, whom they lobbied to evacuate some 300 women and children.
Spence was evacuated to Australia on 11 November, and the 2/2nd commander, Major
Bernard Callinan was appointed Allied commander in Timor. On the night of 30 November / 1 December, the Royal Australian Navy mounted a major operation to land fresh Dutch troops at Betano, while evacuating 190 Dutch soldiers and 150 Portuguese civilians. The launch was used to ferry the passengers between the shore and two
corvettes, and . However, ''Armidale''—carrying the Dutch reinforcements—was sunk by Japanese aircraft and almost all of those on board were lost.

Australian withdrawal, December 1942 – February 1943
By the end of 1942, the chances of the Allies re-taking Timor were remote, as there were now 12,000 Japanese troops on the island and the commandos were coming into increasing contact with the enemy. The Australian chiefs of staff estimated that it would take at least three Allied divisions, with strong air and naval support to recapture the island.
Indeed, as the Japanese efforts to wear down the Australians and to separate them from their native support became more effective, the commandos had found their operations becoming increasingly untenable. Likewise, with the Australian Army fighting a number of costly battles against the Japanese beachheads around Buna in New Guinea, there were currently insufficient resources to continue operations in Timor. As such, from early December Australian operations on Timor would be progressively wound down.
[Dennis 2008, p. 530.]
On 9, 15 and 18 December, the remainder of the original Sparrow Force—except for a few officers—was evacuated with Portuguese civilians, by the Dutch destroyer , under the command of
W. J. Kruys. Meanwhile, in the first week of January, the decision was made to withdraw Lancer Force. On the night of 9/10 January 1943, the bulk of the 2/4th and 50 Portuguese were evacuated by the destroyer . A small intelligence team known as S Force was left behind, but its presence was soon detected by the Japanese. Aided by folboats, with the remnants of Lancer Force, S Force made its way to the eastern tip of Timor, where the Australian-British
Z Special Unit was also operating. They were evacuated by the American submarine on 10 February.
Forty Australian commandos were killed during this phase of the fighting, while 1,500 Japanese were believed to have died.
Aftermath

Overall, while the campaign on Timor had little strategic value, the Australian commandos had prevented an entire Japanese division from being used in the earlier phases of the
New Guinea campaign
The New Guinea campaign of the Pacific War lasted from January 1942 until the end of the war in August 1945. During the initial phase in early 1942, the Empire of Japan invaded the Territory of New Guinea on 23 January and Territory of Papua on ...
while at the same time inflicting a disproportionate level of casualties on them. In contrast to those in Java, Ambon or Rabaul, Australian operations in Timor had been far more successful, even if it was also largely a token effort in the face of overwhelming Japanese strength. Likewise, they had proved that in favourable circumstances,
unconventional operations could be both versatile and more economic than conventional operations, for which the resources were not available to the Allies at that time. Most civilian deaths were caused by Japanese reprisals against the civilian population. The civilian death toll is estimated at 40,000 to 70,000.
Japanese troops released Portuguese POWs in the aftermath of the conquest, in respect to Portugal's neutral status during the war, as the Japanese had done in
