Analysis of information sources in references of the Wikipedia article "Greek War of Independence" in English language version.
On the Greek side, there were the Christian Albanian Souliot bands, hardened mountain fighters based around clan leaders who gradually became integrated into the national war effort. There were also the Albanian-speaking seamen of Hydra and Spetses who provided not only the core of the Greek fleet but also leading members of the Greek government—including one wartime president—who occasionally used Albanian among themselves to prevent others on their own side from reading their correspondence.
