The more substantial Portuguese contingent consisted of 700 regular Brazilian Colonial Army soldiers, led by Lieutenant-General Manuel Marques de Sousa, The First and 550 regular soldiers from the naval infantry of the Colonial Navy of Brazil and several warships to act as transports and provide offshore artillery support. The French defenders were weakened by years of Royal Navy blockade and could only muster 400 regular infantry and 800 unreliable militia, formed in part from the territory's free black population. As a result resistance was inconsistent and despite Cayenne's strong fortifications, the territory fell within a week.

. It had suffered a series of defeats during the war that left it blockaded in its own harbours and unable to put to sea without attack from British squadrons waiting off the coast. Cut off from French trade and supplies, the Caribbean colonies began to suffer from food shortages and collapsing economies, and messages were sent to France in the summer of 1808 requesting urgent help.

Some of these messages were intercepted by the patrolling Royal Navy. Based on the description in those messages of the low morale and weak defences of the Caribbean territories, the decision was taken to eliminate the threat from the French colonies for the remainder of the war by seizing and occupying them in a series of amphibious operations.

. Acknowledging that his force was not large enough to invade the island directly, Yeo decided instead to attack a series of outlying forts on the Mahury River in an effort to draw out the French defenders. On 6 January 1809, preparations were complete and Yeo launched an attack during the night, landing at Pointe Mahury at 03:00 on 7 January in five canoes despite heavy rains, which continued throughout the campaign. The surf was strong and all five canoes were wrecked on the beach, but there were no casualties. Yeo detached a Portuguese force under Major Joaquim Manuel Pinto against the Dégras de Cannes battery while he advanced on Fort Diamant with a force of seamen and marines. Both positions were rapidly carried, the British suffering seven men wounded to French losses of six killed and four wounded. Four cannons were seized, as were 90 French soldiers. Both fortifications were then garrisoned with soldiers from the squadron.

With the capture of the Mahury forts, the French in Cayenne risked being cut off from external help and besieged. In response, Governor Victor Hugues

 mustered most of the 600 troops available to him and marched on the Allied positions. Consolidating his forces at Dégras de Cannes, Yeo demolished Fort Diamant and sent scouts down river, where two further forts were discovered at Trio and the Canal de Torcy. The latter fort had been constructed to defend the approaches to Hugues' residence, which was situated on the canal. Yeo immediately ordered the Portuguese cutters Leão and Vingança into the river to attack the forts, the Portuguese bombarding the positions for an hour while Yeo prepared assault forces. Yeo himself led the attack on the Trio fort while a Portuguese party attacked the fort on the canal. Both positions were captured and their 50 strong garrisons driven off.

As Yeo secured his position from attack from the river, Hugues arrived at Dégras de Cannes. Despite attacking Lieutenant Colonel Marques' garrison immediately, Hugues was unable to defeat the Portuguese before Yeo returned, and was forced to retreat after a three hour engagement. A secondary force sent against Fort Diamant saw the British demolition party on the walls and, assuming the garrison there to be larger than expected, retreated without an assault. The following morning, as Hugues fell back on his residence, Yeo followed, using the river and canal to close with the position. Hugues had fortified his property with 100 men and two artillery pieces, and ordered his men to fire on a party of British sailors offering a truce. A second attempt was met with cannonfire and although a third attempt via one of Hugues' slaves drew a response, the French general's overtures were only an attempt to stall the Allies while his men laid an ambush in the trees near their landing point.

At a signal from one of the artillery pieces, the French ambush party began a heavy fire on the troops advancing up the lane towards the house. Charging forward, Yeo led an attack on the ambushers at the head of his men and in hand to hand fighting seized the house and its artillery. Gathering his forces, Yeo then marched on Cayenne, expecting to meet Hugues at the Beauregard plain, where the French general had stationed his remaining 400 men. Reaching the position on 10 January, Yeo sent two junior officers into Cayenne offering an armistice, which was accepted, Hugues recognising that he was outnumbered and outmanoeuvred. Over the next four days, Yeo's men took the surrender of the outlying French garrisons and units, with the entrance to Cayenne planned for 14 January.

Topaze

To Yeo's consternation, dawn on 13 January showed a sail approaching from the north. This vessel was the French frigate

, a powerful 40-gun vessel that was significantly stronger than any of the British or Portuguese ships in the expeditionary force (the large Infante Dom Pedro having returned to Brazil some time earlier). Topaze had been sent from France under Captain Pierre-Nicolas Lahalle to reinforce the Cayenne garrison in December 1808. In addition to extra troops and military supplies, Topaze's main cargo was 1,100 barrels of flour, Cayenne suffering from severe food shortages due to the British blockade of the French Caribbean. Lahalle was cautious on approaching Cayenne, and soon spotted Confiance at anchor off the harbour.

Confiance, as a 20-gun ship armed with short range carronades, was significantly weaker than Topaze; more critically, she was also almost completely uncrewed, as Yeo had removed all but 25 men and two midshipmen for service with the expeditionary force on land. If Lahalle closed with the ship, the senior officer, Midshipman George Yeo, the captain's much younger brother, would have no option but to surrender, leaving the landing party cut off and at risk of total defeat. Reacting quickly, George Yeo mustered 20 local men, all free black civilians, and pressed them into service to complement his skeleton crew. He then sailed from the harbour in an aggressive manner, as if to confront Topaze. Lahalle was under instructions to avoid combat if it placed his cargo in jeopardy and assumed that such a small vessel would not approach his frigate unless heavier support was hidden nearby, unwilling to risk losing his ship, he turned and sailed north, rapidly outdistancing Confiance and disappearing over the horizon in the belief that the British had already captured Cayenne. Nine days later, as he neared Guadeloupe, Lahalle was spotted by a genuinely larger British squadron and defeated at the Action of 22 January 1809

Aftermath

With his reinforcements driven off and his defences broken, Hugues had no option but to complete his surrender to Yeo. Entering Cayenne on 14 January, Yeo's Anglo-Portuguese force took Hugues' 400 regular soldiers into captivity and collected the arms of 600 white militia and 200 black irregulars, all of whom were allowed to return to their homes. Included in the surrender were 200 cannon, all military and government stores, and all of the various villages and trading posts of French Guiana, which stretched from the Brazilian border to the Maroni River

, which marked the border with the British-held Dutch territory of Surinam.

Casualties in the operation were light, the British losing a lieutenant killed and 23 men wounded, the Portuguese one man killed and eight wounded and the French 16 killed and 20 wounded. The French prisoners were embarked on the expeditionary force's ships and taken to Brazil, and the colony was handed over to the Portuguese government for administration, with the stipulation that it be returned to France at the end of the war. Yeo was highly commended for his leadership during the operation, but his health had suffered during the extended campaigning in late December and was invalided to Rio de Janeiro
