Clifford was the older brother of Harry Kitchen, who had died in hospital in Malta on 2 September 1915. They were the two sons of Thomas and Annie Kitchen of 90 Buxton Road and 17 Heaviley Grove, Stockport and, later, of Ashbourne.
In 1912, he married Sarah Ann Hopkinson at Mount Tabor Church, Wellington Road and they would live at 4 Dial Road, Great Moor. They would have three children but Clifford never got to see the youngest, born on 4 November 1918.
On 28 September 1918, British and Belgian troops attacked in what would prove to be the start of the decisive and final advances in Flanders. After an initial artillery barrage, the troops moved forward at 5.30am. There was little resistance with many Germans surrendering and all the objectives were secured by 8.20am. The attack continued the next day, with the Sherwoods being brought from reserve in the afternoon to attack the enemy positions at Zandvoorde. Again the village was taken with relative ease, although there were some casualties from long-range machine gun fire.
By the end of the day, the battalion had taken up positions just north of the village of Tenbrielen. The next morning, the 30th, other units overlapped the Foresters to continue the advance. At 6.30am, "X" and "Z" Companies went forward in support but the whole Battalion then pulled back into reserve at Tenbrielen where they remained overnight. The next day, they withdrew from this position moving back to reserve camp. Sometime in the previous hours, Clifford had been killed by shellfire.
