This is the brief history of the 22nd Division, a new division formed from Kitchener's volunteers at the beginning of the war. The podcast follows its movements and engagements from its deployment overseas in September 1915, through its brief stay in France and its campaigns in Salonika, until the end of the war.
I recommend using the Long Long Trail website by Chris Baker, if you need to find out which division your chosen unit or soldier served with.
