Ambrogio Spinola was born in Genoa in 1569, the eldest son of Filippo Spinola, Marquis of Sexten and Venafro, and his wife Polissena Grimaldi, daughter of Nicolò prince of Salerno. The family of Spinola was of great antiquity, wealth and power in Genoa. Don Ambrogio's sister Donna Lelia was married to Don Giulio Cesare Squarciafico, 2nd Marquess of Galatone, from whom descend the Princes of Belmonte.
The houses of Spinola and Doria were rivals for authority within the republic. Ambrogio Spinola continued the rivalry with the count of Tursi, then the chief of the Dorias. He was not successful, and having lost a lawsuit into which he had entered to enforce a right of pre-emption of a palace belonging to the Salerno family which the Doria wished to purchase, he decided to withdraw from the city and advance the fortunes of his house by serving the Spanish monarchy in Flanders. In 1602 he and his brother Frederick entered into a contract with the Spanish government - a "condotta" on the old Italian model. It was a speculation on which Spinola risked the whole of the great fortune of his house. Ambrose Spinola undertook to raise 9000 men for land service, and Frederick to form a squadron of galleys for service on the coast.
Several of Federico's galleys were destroyed by English and Dutch war-ships; first at Sesimbra in June and then in October in the Channel. He himself was slain in an action with the Dutch on 24 May 1603. Ambrogio Spinola marched overland to Flanders in 1602 with the men he had raised at his own expense. During the first months of his stay in Flanders the Spanish government played with schemes for employing him on an invasion of England, which came to nothing. At the close of the year he returned to Italy for more men. His experience as a soldier did not begin until, as General, and at the age of thirty-four, he undertook to continue the Siege of Ostend on 29 September 1603. Despite failing to relieve Sluis under siege at the same time, the ruinous remains of Ostend fell into his hands on 22 September 1604.
The governor of Flanders Archduke Albert and the Infanta Clara Eugenia, daughter of Philip II, who had set their hearts on taking Ostend, were delighted at Spinola's success, and it won him a high reputation among the soldiers of the time. On the close of the campaign he went to Spain to arrange with the court, which was then at Valladolid, for the continuance of the war. At Valladolid he insisted on being appointed commander-inchief in Flanders. By the 9th of April he was back at Brussels, and entered on his first campaign. The wars of the Low Countries consisted at that time almost wholly of sieges, and Spinola made himself famous by the number of places he took in spite of the efforts of Maurice of Nassau to save them.
In 1606 he again went to Spain. He was received with much outward honour, and entrusted with a very secret mission to secure the government of Flanders in case of the death of the archduke or his wife, but he could not obtain the grandeeship which he desired, and was compelled to pledge the whole of his fortune as security for the expenses of the war before the bankers would advance funds to the Spanish government. As he was never repaid, he was in the end utterly ruined. The Spanish government began now to have recourse to devices for keeping him away from Spain. Until the signing of the twelve years' truce in 1609 he continued to command in the field with general success. After it was signed he retained his post, and had among other duties to conduct the negotiations with France when the prince of Conde fled to Flanders with his wife in order to put her beyond the reach of the senile admiration of Henry IV of France.
By 1611 Spinola's financial ruin was complete, but he obtained the desired Grandeza. In 1614 he had some share in the operations connected with the settlement of Cleves and Jülich. On the outbreak of the Thirty Years' War he made a vigorous campaign in the Lower Palatinate which included the sacking of many towns and villages, including Drais, and was rewarded by the grade of Captain-General.
After the renewal of the war in the Low Countries in 1621 he gained the most renowned victory of his career, namely the capture of Breda. Success came after a long siege (28 August 1624 – 5 June 1625), in spite of both objection of Philip IV of Spain who thought the siege too risky and expensive, and the most strenuous efforts of Maurice of Nassau, Prince of Orange to save it. The surrender of Breda is the subject of the great picture by Velázquez, known as Las Lanzas; the portrait of Spinola is from memory.
The taking of Breda was the culmination of Spinola's career. Utter want of money paralysed the Spanish government, and the new favourite, Olivares, was jealous of the general. Spinola could not prevent Frederick Henry of Nassau from taking Groll, a good set-off for Breda. In January 1628 he left for Spain, resolved not to resume the command in Flanders unless security was given him for the support of his army. At Madrid he had to endure much insolence from Olivares, who endeavoured to make him responsible for the loss of Groll. Spinola was resolute not to return to Flanders.
Meanwhile the Spanish government added a war over the succession to the duchy of Mantua to its other burdens. Spinola was appointed as plenipotentiary and general. He landed at Genoa on the 19th of September 1629. In Italy he was pursued by the enmity of Olivares, who caused him to be deprived of his powers as plenipotentiary.
Spinola's health broke down, as he was already 61 years old, with over 30 years experience in the battle fields, and died on 25 September 1630 at the Siege of Casale, muttering, apparently, the words "honour" and "reputation. "
The title of "marquis of Los Balbases", still borne by his representatives in Spain, was all that his family received for the vast fortune they spent in the service of Philip III and IV.
He was appointed a Knight of the Order of the Golden Fleece in 1605.
He would be painted however after his death, by Diego Velázquez, in 1635, as ordered by Felipe IV, in the famous picture "The Surrender of Breda", visited by tens of millions of tourists at the Museum of Prado in Madrid for the last two centuries or so.
Spinola was a brilliant field commander, whose daring in battle often was used to outflank his opponents and catch them off guard. He was not a great technical innovator, but was a master of military skills. He used rapid movement and pell-mell actions in his battles. He was skilled at picking out an enemy's weakest spot and applying force there to achieve victory.
In 1592 he was married to Giovanna Bacciadonne. They had three children
She was a daughter of the count of Galerata.
She married Diego Felipez de Guzmán, 1st Marquis of Leganés, Governor of Flanders.
He was born in 1594 and died in Madrid, Spain, on the 8th of August 1659.
He was born in 1597 and died in 1649.
