Civilian casualty ratio
Some 7 million combatants on both sides are estimated to have died during World War I, along with an estimated 10 million non-combatants, including 6.6 million civilians. The civilian casualty ratio in this estimate would be about 59%. Boris Urlanis notes a lack of data on civilian losses in the Ottoman Empire, but estimates 8.6 million military killed and dead and 6 million civilians killed and dead in the other warring countries. The civilian casualty ratio in this estimate would be about 42%. Most of the civilian fatalities were due to famine, typhus, or Spanish flu rather than combat action. The relatively low ratio of civilian casualties in this war is due to the fact that the front lines on the main battlefront, the Western Front, were static for most of the war, so that civilians were able to avoid the combat zones.
Gloucestershire Regiment in World War I
1st Battalion spent a week in the line near High Wood at the end of August, during which time it endured the most intense shelling it experienced in the whole war. After three days the trenches were practically obliterated, forcing the men into the shell holes in front of them, and by the time the battalion was relieved on 28 August it had lost 46 killed and 141 wounded. On 8 September the battalion joined the 2nd Welch and 9th Black Watch in an attack which carried the German second line in High Wood, but a lack of reinforcements forced them to withdraw. The attack cost 1st Battalion 3 officers (amongst them the commanding officer Lieutenant-Colonel Pagan), of whom 5 were killed, and 206 other ranks, of whom 84 were killed, leaving the battalion with just 4 officers and 96 other ranks fit for duty. The next day 10th Battalion suffered 122 casualties in a failed attack through the northwest corner of the wood.
