Editing 2nd Mounted Division (section)

===Gallipoli===
The division landed at "A" Beach, [[Landing at Suvla Bay|Suvla Bay]] on the night of 17 August / morning of 18 August and moved into reserve positions at Lala Baba on the night of 20 August. On 21 August it advanced to Chocolate Hill under heavy fire and took part in the attack on Hill 112.<ref name=WestlakeGal>{{harvnb|Westlake|1996|pp=250–283 passim}}</ref>

Due to losses during the [[Battle of Scimitar Hill]] and wastage during August 1915, the division had to be reorganised.{{efn|At this time, a cavalry or yeomanry regiment had a strength of 550 officers and men.  Having left a party of 100 officers and men in Egypt, they would have landed in Gallipoli no more than 450 strong, or about 6,300 for the 14 regiments.  This would be about half the strength of an infantry division (12 battalions of 1,000 officers and men).}} On 4 September 1915, the [[1st Composite Mounted Brigade]] was formed from the 1st, 2nd and 5th Mounted Brigades, and the [[2nd Composite Mounted Brigade]] from the 3rd and 4th Mounted Brigades.<ref name=Becke17>{{harvnb|Becke|1936|p=17}}</ref>  Each dismounted brigade formed a battalion sized unit, for example, 1st South Midland Regiment ([[Warwickshire Yeomanry|Warwickshire]], [[Royal Gloucestershire Hussars|Gloucestershire]] and [[Queen's Own Worcestershire Hussars|Worcestershire Yeomanry]]).<ref name=Becke13>{{harvnb|Becke|1936|p=13}}</ref>

The [[Scottish Horse Mounted Brigade]] landed as Suvla on 2 September and joined the division.  Likewise, the [[Highland Mounted Brigade]] joined the division after landing on 26 September.  Both brigades were dismounted in the UK before sailing directly for Gallipoli.<ref name=Becke14/>
