[...] On the dawn of 18/31 May 1918, the Archipelago division of the National Defence Army Corps launched an attack against the Bulgarian fortifications of Skra. The divisions of Serres and Crete held an auxiliary part. Five hundred and eighty cannons of every range prepared and supported the charge.

Officers, commanders, soldiers were competing as to would die first. Their victory has been complete. The Bulgarian front has been overthrown for a width of twelve kilometres and a depth of approximately two kilometres. One thousand and eigth hundred Bulgarians and forty officers have been taken prisoners. Only the Archipelago division had 24 officers and 314 privates dead, one thousand and eight hundred injured. The total casualties of the Greeks exceeded three thousand.
The impetus, self-sacrifice but also the insistence of the until yesterday volunteers took by surprise their foreign partners. The commander of operations French general Gerome said in his dispatch:
"The Greeks achieved all their objective aims in a front of twelve kilometres. They demonstrated from beginning to end of the operation high military virtues. The general commanding them is proud to have such men ".
The Field Marshal of Thessaloniki Guillaumat, summoned after a while in Paris as military commander of the metropolis, announced to Romanos:
"The victory of Skra is for me an achievement equally glorious to the capture of Mortom before Verdun.
"As soon as the Greek army gets together in Macedonia, it will be possible to deliver a decisive blow against the Bulgarian army, which is in a very bad state.
"The Greek army, the value of which was known and which gave anew proofs of its bravery, has a glorious future before it".
Clemenceau himself said to the Greek ambassador:
"You comprehend my joy, when I tell you that general Guillaumat praised the Greek army".
The most serious among the French military reviewers concludes as late as 1929 about the importance of the Greek victory:
"The success of Skra was an eye-opener for the Allies about two facts, which should not go unnoticed: the collapse of the Bulgarian endurance and the value of the Greek troops".
