Mucip Kemalyeri in his book entitled 'How the Spirit of Gallipoli was born and the Azerbeycan Wars' mentions Major Halis in a few pages. The references as 'Commander' and the orders that Kemalyeri receives are key elements that validate Kemalyeri as under the command of Halis:

"During our short stay in the Anzak Cove the messenger corresponded notifying us of our current status.

As time went by, our current situation was disintegrating getting worse than worse. Thereafter during our stay in the Anzak Cove, Commander Halis emerged.

I was only 20 years old at the time and his mere presence rejuvenated me. The enemy too, was slowly probing our status. Shortly after, he gave each soldier to carry out specific orders - once he gave me my orders, he made the following statement to all that were present:
 

'It appears as if the enemy will drift away into the sea'.

His face however was transforming to a more yellowish color.

Ironically, his vicious eyes were slowly dwindling, yet I saw the cloth of his left arm ripped severely through his bruising skin and saw the blood dripping down towards his fingertips.

I attempted to make some sort of sense of this paradox, but felt no need for it given the circumstances.
 

But curious me, just felt the need to ask: 'Commander - you are injured'.

He then said: 'Not to worry - it happend on the way here.'.

I felt it neccessary to get the surgeon. I was stopped by Commander Halis and he ordered me to not speak of what truely happen. He ordered me to:

 '...dare not mention anything to the soldiers of my injuries'.

He was hurt in combat. Perhaps the reason for him saying this is not to lower the soldiers confidence.
 

Despite the severity of his injuries, Commander Halis and a few soldiers were in patrol eyeing for any sudden possible attack. As each minute passed by, I felt his pain and saw that he was begining to loose focus. During his exchange with us, I could feel his sophistication but in reality he too was scared and this concerned me.

He then gave the following order: 'All men must stand there ground and under no circumstance must they withdraw back - Only send a messenger for your current status and if our situation worsens, then I will have reinforcement'"

Major Halis is mentioned again on page 49:

"The 3rd Batallion's 3rd and 4th Squadrons attacked from the right. The attack continued from the North-Western and followed the enemy. However, upon reaching Baby 700 and Mule Valley they encountered a much more greater challenge.

All forces there were really close to one another. 3rd Batallion Commander Major Halis, being injured withdrew from the region. 4th Squadron commander Galip of the Cengel Village was already out of the picture, because as soon as the attacks began he was hurt.

 When the Batallion commander returned from his injuries, he returned to the same region

to give more reinforcements especially where the 4th Squadron was located.

The Batallion Commander gave the young substitute lieutenant officer an opportunity to show his talent. Also, a young fellow by the name of Medeni was in it as well. These two youngsters proved themselves; they did not allow the enemy to approach any closer that they already were.

Finally, Kemalyeri also mentions Major Halis also in paragraph 5, on page 50.
