 There are still today no reliable statistics related to the numbers of, for example, the total of the war casualties.However based upon historical registration and contemporary reports of some battles of this war as well as upon the admitted numbers in similar fights that happened in these times around the globe, and considering how long the Brazilian independence war lasted (22 months), estimates of all killed in action on both sides are placed from around 5,700 to 6,200.The last Portuguese soldiers left Brazil in 1824.
