which regiment suffered losses during the battle of mametz wood
Mametz Wood Memorial The 14th (Swansea) (Service) Battalion, the Welsh Regiment, went into the attack with 676 men and after a day of hard fighting had lost almost 400 men killed or wounded before being relieved. Other battalions suffered similar losses. However, by 12 July the wood was effectively cleared of the enemy. The Welsh Division had lost about 4,000 men killed or wounded in the engagement. It would not be used in a massed attack again until 31 July 1917.
Siege of Vicksburg The successful ending of the Vicksburg Campaign significantly degraded the ability of the Confederacy to maintain its war effort, as described in the Aftermath section of the campaign article. Some historians—e.g., Ballard, p. 308—suggest that the decisive battle in the campaign was actually the Battle of Champion Hill, which, once won by Grant, made victory in the subsequent siege a foregone conclusion. This action (combined with the surrender of Port Hudson to Maj. Gen. Nathaniel P. Banks on July 9) yielded command of the Mississippi River to the Union forces, who would hold it for the rest of the conflict.
