On November 28 the Spanish schooner "Monserrate" arrived in Puerto Rico from Macao with the news that the supply aid requested by Ramírez would soon reach Montes.

With their positions quickly forming, twenty nine soldiers, including General Ramírez, reached the port at the mouth of the river at Boca de Yuma to receive the military aid sent from Puerto Rico by Governor Montes.

The war materials had been shipped in the brig Frederick and schooner Render and consisted of a gunboat, four rifles with bayonets, a hundred sabers, and corresponding ammunition.

He urged taking the French garrison at Samaná (Sabana de la Mar) for making a stronghold, because without the possession of this port the Reconquista forces could fail.

Ramírez took note of the presence of allied British warships off the Santo Domingo coastline, and dispatched a messenger to Charles Dashwood who was commanding the frigate HMS Franchise.

As one of the few reconquistadores that had knowledge of war tactics, Ramírez was entrusted to direct the transfer of weapons and baggage to El Seibo from the port.

Then Diaz was in charge of organizing the conflict's meeting site, the enlistment of weapons, and choosing the most advantageous position to wait out the approaching enemy.

On the morning of November 3, Lieutenant Diaz began organizing and distributing arms and ammunition to his forces at the Port of Higuey in Boca de Yuma.

Ferrand ignored the real warnings that Ramírez's forces were not to be underestimated, especially in their deft handling of the knife, and happily prepared to give battle.

Lieutenant Díaz resolved to take on preparatory measures himself on the night of November 6, before the morning date announced by Governor General Ferrand for French entry into El Seibo.

General Ramírez and Lieutenant Díaz provided guns with dry amunicionar ammunition and bayonets, for the foot and horsemen troops.

He warned that their action would be decisive, since coming to the front of the French enemy with their governor's cream of the forces at his disposal, whose defeat would mean the triumph of the Reconquista campaign.

Riders led by Captain Antonio Sosa wasted no time and ran to meet them, forcing the attackers to pull in the flanges.

Among many other provisions, José de la Rosa was to ambush thirty riflemen at the rear of the enemy to distract attention after the fire broke out front.

General Ramírez gave the cavalry of his right wing, led by Captain Vicente Mercedes, the order to advance, an operation that was executed very quickly, overwhelming the French enemy.

With the displayed waste of their battalions, French Governor General Ferrand ordered a hasty return to the city of Santo Domingo with a group of surviving officers.

Don Diego Polanco, was formed to appoint as acting governor Sanchez Ramirez and to recognize King Ferdinand VII as sovereign of the colony conquered.
