At the end of April Birdwood told GHQ MEF (General Headquarters Mediterranean Expeditionary Force) that he could not land 6,000 horses at Anzac Cove as there was no water for them. GHQ MEF was unhappy that the ANZAC force would be immobilised on the beachhead, but they would have been no use. Some of the thousands of men and horses remained on board ship for up to a month. Birdwood signalled on 17 May that 17 transports would be returning to Alexandria to offload 5,251 horses accompanied by 3,217 men. GHQ MEF insisted that some of the men remain in Alexandria to look after the horses and guard ANZACs ""many vehicles and mountains of baggage"".
