In 1861,
Spanish forces invaded the island. The Spanish kept him as commander of the square, but when the uprising led by
Juan Nouesí, of August 27, 1863, De Lora was sent to repress and suffocate him. The patriots invited him to join the movement, De Lora accepted and was recognized on the spot as head of the restorative columns in Puerto Plata. The Spanish, surrounded in the
San Felipe Fortress, were under the threatening siege of the patriots when reinforcements from
Cuba and
Puerto Rico arrived in the night of the same August 27 and based on their material superiority, they evicted the nationals from the urban area and forced them to retreat to the fields. The resistance in Puerto Plata was under the command of Nouesí, while De Lora marched to Santiago, where the battle for control of the city was being fought. He arrived via the Jamao route, joined the fight and in the decisive moments of the hard day September 6, 1863, he advanced with his men through the General Valverde Street, (today San Luis), taking a trench of the enemy. He fought with deadly intensity. The downloads rifle and cannon were made at point-blank range, and the besieged repelled the assailants with their points of the bayonets and with streams of shrapnel, as
Gregorio Luperón narrates. == Death ==
