Here is a medal from my collection which I am in the process of researching. It was awarded to a 6376 Company Sergeant Major/Colour Sergeant of the The Rifle Brigade.
I have purchased his Medal Index Card and it states he arrived in France on 20.12.14, but the only Battalion to land in France that month was the 4th and they arrived in France on 21.12.14.
So I would assume that he was with the 4th Battalion and someone made a mistake on his medal index card? As to me it doesn't make much sense to me to send a senior NCO to France without his men?
So assuming he was with the 4th Battalion he would have come under the command of 80th Brigade in 27th Division. If that is so, the Division subsequently took part in these actions:
The action of St Eloi
The Second Battle of Ypres
The Division was ordered to Salonika in November 1915 and embarkation began on 17 November, but it was not until 13 February 1916 that the last of the Division finally arrived.
30 September - 2 October 1916: the capture of Karajakois
3-4 October 1916: the capture of Yenikoi
17 November and 6-7 December 1916: the battle of Tumbitza Farm
14 October 1917: the capture of Homondos
The Division lost a number of units in mid 1918; they were transferred to France
1-30 September 1918: the final offensive in Salonika, including the capture of the Roche Noir Salient (1-2 September), the passage of the Vardar river and pursuit to the Strumica valley (22-30 September)
Hostilities with Bulgaria ceased on 30 September, with the Division by then in the area Kosturino - Rabrovo - Cestovo. The Division continued to advance and passed Krupnik by the end of October. 27th Division was ordered to halt and turn about on 2 November, embarking in December for operations on the Black Sea. It reached Constantinople on 19 December and opened HQ at Tiflis in January 1919. The Division was not disbanded until 24 September 1919, by which time it was at Batum.
So, that is all I have so far. I would really appreciate it if some one could help fill in the gaps.
And a big thank you for Ade for showing me the website which made my research possible.
