Talk:Brazilian ironclad Rio de Janeiro

Apa River
When she struck the mine it can't have been in the Apa River -- not the one in the Mato Grosso anyway -- because that's nowhere near Curuzú, and anyway was inaccessible to the Brazilian Navy until after the Passage of Humaitá. It may be that your source Graz says so, but that doesn't validate a geographical impossibility. In a Good Article, this really needs attention! Thanks.Ttocserp 10:15, 10 May 2016 (UTC)
