Thanks for all your kind replies!
This is the kind of collection you can´t plan. The opportunity to get a new medal may appear only once...but when it happens it´s a celebration day
Let´s see some more medals...
Forte de Coimbra Medal, a 1775 fortification located on Mato Grosso - scenario of a huge battle during the war when paraguayans invaded that region.
Matto Grosso Medal - This is the "bloodiest" medal of the period.
" Brazil sent an expedition to fight the invaders in Mato Grosso. A column of 2,780 men led by Colonel Manuel Pedro Drago left Uberaba in Minas Gerais in April 1865, and arrived at Coxim in December after a difficult march of more than two thousand kilometers through four provinces. But Paraguay had abandoned Coxim by December. Drago arrived at Miranda in September 1866 – and Paraguay had left once again. In January 1867, Colonel Carlos de Morais Camisão assumed command of the column, now with only 1,680 men, and decided to invade Paraguayan territory, where he penetrated as far as Laguna. The expedition was forced to retreat by the Paraguayan cavalry.
Despite the efforts of Colonel Camisão's troops and the resistance in the region, which succeeded in liberating Corumbá in June 1867, Mato Grosso remained under the control of the Paraguayans. They finally withdrew in April 1868, moving their troops to the main theatre of operations, in the south of Paraguay.
