Passage: The Confederation-controlled Ava was next. Bayinnaung made extensive preparations, assembling a large invasion force . In December 1554, the Toungoo land and naval forces invaded. Within a month, the invasion forces held complete command of the river and the country. On 22 January 1555, the southern forces took the city. Bayinnaung then planned to follow up to the Confederation's home states to prevent future Shan raids into Upper Burma. With the entire Irrawaddy valley under his control, he was able to raise a large army of 24,000 men, 1200 horses and 60 elephants, and invaded the Shan states in January 1557. The massive show of force worked. Shan states one after another submitted with minimal resistance. By March 1557, Bayinnaung in one stroke controlled all cis-Salween Shan states from the Patkai range at the Assamese border in the northwest to Mohnyin , Mogaung in present-day Kachin State to Momeik Thibaw , and Mone in the east.

Passage: Duke Magnus Birgersson proclaiming himself king of Sweden, refused to pay the agreed sum of 6,000 marks of silver and complained about the ravages the Danish Assistance Force allegedly committed. Instead, he started a war by moving into the then Danish provinces of Halland and Skane by total surprise in the fall of 1276.The Danes mobilized an army under marsh Uffo that stopped the Swedish army who then fled Scania. The next year Danish forces marched on Smaland in retaliation for their depredations in Halland and Skane. The Danish punitive expedition followed the scarce Swedish Defense Forces into Vastergotland, where they met a Swedish part of the army of about 200 knights in armour, led by Ulf Karlsson. The Battle of Ettak was a defeat for the Danish army who were surprised in their own camp. Erik Klipping gathered a large army in 1277 and went into Vastergotland which again was overcome and looted. The fortresses of Axwall and Skara was captured by the Danish army. Eric V of Denmark decided to end the campaign because it was not meant as anything other than an act of revenge in response to the Swedish king's assault on Halland and Skane. After returning home, Eric V of Denmark began negotiations with the Swedes leading to a peace agreement in Laholm, Scania in early 1278. Magnus Birgersson had to pay war reparations which were reduced from 6,000 to 4,000 marks of silver.
