question: In South America , the Portuguese conquered from Spain most of the Rio Negro valley, and repelled a Spanish attack on Mato Grosso . Between September 1762 and April 1763, Spanish forces led by don Pedro Antonio de Cevallos, Governor of Buenos Aires  undertook a campaign against the Portuguese in Uruguay and South Brazil. The Spaniards conquered the Portuguese territories of Colonia do Sacramento and Rio Grande de São Pedro and forced the Portuguese to surrender and retreat. Under the Treaty of Paris , Spain had to return to Portugal the colony of Sacramento, while the vast and rich territory of the so-called "Continent of S. Peter"  would be retaken from the Spanish army during the undeclared Hispano-Portuguese war of 1763-1777. As consequence of the war the Valdivian Fort System, a Spanish defensive complex in southern Chile, was updated and reinforced from 1764 onwards. Other vulnerable localities of colonial Chile such as Chiloé Archipelago, Concepción, Juan Fernández Islands and Valparaíso were also made ready for an eventual English attack.
Answer this question: What was the last year of the "Continent of S. Peter" was to be retaken from the Spanish army?

question: On 22 December the Pretender landed in Scotland at Peterhead, but by the time he arrived at Perth on 9 January 1716, the Jacobite army numbered fewer than 5,000. In contrast, Argyll's forces had acquired heavy artillery and were advancing quickly. Mar decided to burn a number of villages between Perth and Stirling, so as to deprive Argyll's army of supplies. On 30 January Mar led the Jacobites out of Perth; on 4 February the Pretender wrote a farewell letter to Scotland, sailing from Montrose the following day. Many Jacobites who were taken prisoner were tried for treason and sentenced to death. The Indemnity Act of July 1717 pardoned all those who had taken part in the Rising, but the whole of the Clan Gregor, including Rob Roy MacGregor, was specifically excluded from the benefits of that Act. Another attempt, this time with Spanish support, was undertaken in 1719, only to end again in defeat in the Battle of Glenshiel. James's son Charles Edward Stuart attempted to win the throne for his father in 1745, in another Jacobite rising, but was defeated at the Battle of Culloden. James died in 1766.
Answer this question: When didMar lead the Jacobites out of Perth?
answer: 1716-January-30

question: Against the Polish line the Red Army gathered its Northwest Front led by the young General Mikhail Tukhachevsky. Their numbers exceeded 108,000 infantry and 11,000 cavalry, supported by 722 artillery pieces and 2,913 machine guns. The Soviets at some crucial places outnumbered the Poles four-to-one.Tukhachevsky launched his offensive on 4 July, along the Smolensk-Brest-Litovsk axis, crossing the Auta and Berezina rivers. The northern 3rd Cavalry Corps, led by Gayk Bzhishkyan , were to envelop Polish forces from the north, moving near the Lithuanian and Prussian border . The 4th, 15th, and 3rd Armies were to push west, supported from the south by the 16th Army and Mozyr Group. For three days the outcome of the battle hung in the balance, but Soviet numerical superiority proved decisive and by 7 July Polish forces were in full retreat along the entire front. However, due to the stubborn defense by Polish units, Tukhachevsky's plan to break through the front and push the defenders southwest into the Pinsk Marshes failed.
Answer this question: Did the Red Army have more infantry or cavalry?
