Went to check again the location for the Elmore capture and imprisonment.
As stated in history, he tried to blow up 50 cavalry and soldiers sent by Baquedano to check on th railway conditions so he could send the whole chilean army down to Arica from Tacna via train and Elmore's mission was to blow up the railroad to delay the advance of the chileans.
While in Chacalluta valley up north of Arica, he stumbled upon the bunch of horses and soldiers and tried to blow them up and after it he was captured.
Now this is a perfect location and also am happy for I got myself 40 horses with riders and a bunch of soldiers to shoot these scenes. The remaining ten will be computer generated.
