 At 05 : 45 , Lieutenant @-@ Colonel <unk> Sefik of the Turkish 27th Infantry Regiment received orders to move his 1st and 3rd Battalions to the west and support the 2nd Battalion around Gaba Tepe . The two battalions were already assembled , having spent that night carrying out military exercises . They could not be sent to Ari Burnu as it was not marked on the Turkish maps . Colonel <unk> Sami , commanding the 9th Division , also ordered the division 's machine @-@ gun company and an artillery battery to move in support of the 27th Infantry Regiment , followed soon after by an 77 mm artillery battery . At 08 : 00 Lieutenant @-@ Colonel <unk> Kemal , commanding the 19th Division , was ordered to send a battalion to support them . Kemal instead decided to go himself with the 57th Infantry Regiment and an artillery battery towards Chunuk Bair , which he realised was the key point in the defence ; whoever held those heights would dominate the battlefield . By chance , the 57th Infantry were supposed to have been on an exercise that morning around Hill 971 and had been prepared since 05 : 30 , waiting for orders .
