in this site there's a map of the Iberian Peninsula.
I made this map because Portugal was an important state in ww1.
on march 9th 1916 Germany declared war against Portugal; during the war 115 merchant ships were sunk by german u-boats, but importan were the destroyers and the armed merchant cruisers that sank a lot of german and K.u.K. ships in mediterranean sea and atlantic oceans and the famous "Action of 14 octouber 1918" where the u-cruiser U-139 sank the portuguese armed drifter NRP Augusto Castilho.
These are the mayor warships of portuguese navy:
Adamastor class CL
Tejo class DD (similar than the italian Audace class)
Douro class DD
armed drifters
