Passage: In 1915, during World War I, British and South African forces occupied it in the so-called South West Africa Campaign, and SW Africa later became a protectorate of South Africa. On 16 August 2004, 100 years after the war, the German government officially apologized for the atrocities. "We Germans accept our historic and moral responsibility and the guilt incurred by Germans at that time," said Heidemarie Wieczorek-Zeul, Germany's development aid minister. In addition, she admitted that the massacres were equivalent to genocide. Not until 2015 did the German government admit that the massacres were equivalent to genocide and again apologized in 2016. The Herero are suing the German government in a class action lawsuit.

Passage: On 11 February 1727 Spain, under command of the Marquis de las Torres and supervision of Chief Engineer of the Spanish Royal Engineer Corps Marquis of Verboom, laid siege to the city . Depending on the sources, Spanish troops were between 12,000 and 25,000. British defenders were 1,500 at the beginning of the siege, increasing up to about 5,000 by troops brought from overseas by a fleet commanded by Charles Wager. After a four-month siege, with several unsuccessful and costly attempts, Spanish troops gave up and retired on 12 June. Spain had lost over 1,400 men while the British had suffered around 300 casualties. The Spanish had expected material help from the Austrians promised under the Treaty of Vienna, but they received little. They had been outmanoeuvred by British diplomats, who had concluded a secret deal with the Austrians to prevent them intervening.

Passage: The intervention of Denmark, Sweden and Poland-Lithuania into Livonia began a period of struggle for control of the Baltic, known contemporaneously as the dominium maris baltici. While the initial war years were characterised by intensive fighting, a period of low-intensity warfare began in 1562 and lasted until 1570 when fighting once more intensified. Denmark, Sweden and to some extent Poland-Lithuania were occupied with the Nordic Seven Years' War  taking place in the Western Baltic, but Livonia remained strategically important. In 1562, Denmark and Russia concluded the Treaty of Mozhaysk, respecting each other's claims in Livonia and maintaining amicable relations. In 1564, Sweden and Russia concluded a seven-years truce. Both Ivan IV and Eric XIV showed signs of mental disorder, with Ivan IV turning against part of the Tsardom's nobility and people with the oprichina that began in 1565, leaving Russia in a state of political chaos and civil war.
Question: How many years did the period of low-intensity warfare last?
