[7][8] By late July, a full-on offensive was being carried out by Peru in the coastal region of southern Ecuador, and fire was being once again (hostilities had occurred in the past)[4] exchanged in the disputed Amazon as well.

[6] At the time, both outposts were located in what was known as the Status quo line, agreed upon by both countries in 1936 to serve as a provisional border, and were separated by an eponymous bridge.

[9] During the battle, Major Arias attempted to negotiate a ceasefire but was unsuccessful in doing so as the Peruvians demanded an unconditional surrender, something he was not authorized to approve.

[2] The battle went on for hours, and the Ecuadorian forces were eventually forced to retreat, with Peru eventually overrunning the outpost and capturing several men, including Arias,[3] and by 12 p.m. the Flag of Peru had been risen on the Ecuadorian outpost, ending the battle.

[3] Ecuadorian accounts claim that the men had to leave almost naked and extremely unprepared, and that due to the harsh nature of the local environment, six children drowned.
