Question: What country is Stockholm located in? Passage 1:The death of his father, Dom Luiz de Mello, drove him early to soldiering, and having joined a contingent for the Flanders war, he found himself in the historic storm of January 1627, when the pick of the Portuguese fleet suffered shipwreck in the Bay of Biscay. He spent much of the next ten years of his life in military routine work in the Iberian Peninsula, varied by visits to the court of Madrid, where he contracted a friendship with the Spanish poet Quevedo and earned the favor of the powerful minister Olivares. In 1637 the latter despatched him in company with the conde de Linhares on a mission to pacify the revolted city of Évora, and on the same occasion the duke of Braganza, afterwards King John IV (for whom he acted as confidential agent at Madrid), employed him to satisfy Philip III of Portugal of his loyalty to the Philippine Dynasty.

 Passage 3:Upon his return from abroad in 1698, Peter the Great began preparations for the war with Sweden. The first Russian regular regiments consisted of the so-called datochniye lyudi (lifelong conscripts), later combined with the okhochiye lyudi (volunteers). Peter managed to muster 27 regiments formed into three divisions (9 regiments each). Generals Adam Veyde, Avtonom Golovin and Anikita Repnin were appointed commanders of these divisions. Soldiers had to learn how to use weapons and master military formations in accordance with Veyde's Military Charter (1698). Foreign officers were in charge of this training, which caused Golovin's anger. He used to say that they couldn't hold a musket in their hands, didn't know their business, had to be taught themselves, and that it was all a waste of time. Soon, Peter the Great had to decline their services and put inexperienced Muscovite sluzhiliye lyudi in charge of the training. In 1700, Golovin formed 8 infantry regiments and one dragoon regiment (one division). During the Battle of Narva, the Russian army was defeated by Charles XII. Golovin's division (which consisted of recruits only) was one of the first ones to flee the battlefield. Field Marshal Charles Eugène de Croÿ and all of the foreign officers in the Russian army surrendered to the Swedes. They were soon followed by Generals Yakov Dolgoruky, tsarevich Alexander Imeretinsky, Avtonom Golovin and Ivan Buturlin, who had decided to capitulate, as well. As a result, almost all of the commanding officers were taken prisoners and the Swedes captured all of the Russian artillery, which Peter the Great had been assembling piece by piece from all over Russia. Golovin was taken to Stockholm and remained there for the next 18 years. The tsar was only able to exchange him in 1718. In 1719 and 1720, Golovin took part in the structuralization of the Russian army.
