Private Isaac Tanner, 1st Battalion Coldstream Guards, was killed in action at the Battle of Inkermann, 5 November 1854. Not listed in the published casualty roll but with copied roll and casualty returns extracts which confirm KIA Inkermann.

The Coldstream Guards, when they retired from the Two-gun Battery, leaving about 100 wounded behind, were maddened to perceive that the instant the enemy occupied the place they commenced massacring all the poor defenceless objects. The conduct of the Coldstream Guards should immortalize their name. They fought literally to the death. They went into action with 16 officers and about 400 men, and out of this small number had 8 officers killed, 5 wounded, and upwards of 200 rank and file killed and wounded. The Grenadiers and Fusiliers also performed prodigies. On the whole, the brigade of guards lost 13 officers killed, 15 wounded, and 580 rank and file, out of about 1,600 men engaged. The Coldstreams charged the enemy at the point of the bayonet eleven times. At each time the Russians crossed bayonets, and fought fiercely, but were slaughtered like sheep by our gallant fellows. The three battalions of Guards now barely mustered 1,000 effective men.
