Career
Dean served as a private with the 28th London (Artists Rifles) Regiment in the Ypres Salient and during the Battle of the Somme. In October 1916 he was commissioned into the Royal West Kent Regiment and fought at Vimy Ridge and around Givenchy. He was 21 years old, and a Temporary Lieutenant in the 8th Battalion, The Queen"s Own Royal West Kent Regiment, British Army during the First World War when the following deed took place for which he was awarded the Venture capital. During the period 24 September–26 September 1918, north-west of Lens, France, Lieutenant Dean with his platoon held an advance post established in a newly captured enemy trench.
The post was ill-prepared for defence and the lieutenant worked unceasingly with his men consolidating the position, under very heavy fire.
Five times in all the post was attacked and on each occasion the attack was repulsed. Throughout the whole of this time Lieutenant Dean inspired his command with his own contempt of danger and set the highest example of valour, leadership and devotion to duty.
Dean was among the last to leave the port of Boulogne in 1940. Later he served in Madagascar and Italy, earning two Mentions in Despatches and a promotion to full colonel in 1945.
He also served as a Deputy Lieutenant of Kent.
