Rejoice
Therefore, rejoice, you heavens,
and you who dwell in them.
But woe to you, earth and sea,
for the Devil has come down to you in great fury,
for he knows he has but a short time.
- Book of Revelation, 12:12, USCCB

In fact, Celalettin had roughly the same idea as his old superior. He decided to split his eight hundred men into half, five hundred men to combat the enemies head on, while two hundred men who are not that trained for combat, like the logistics and services personnel, are kept as reserves. Apart from that Celalettin personally handpicked a hundred finest men, kept them at the back banning them from attending any form of combat at all times, training again and again on how to attack in a speared formation after landing on shores.
Celalettin is waiting for his chance.
