The soldiers at Sebastopol were not long in learning that amongst their officers there was one slight, wiry young lieutenant of sappers, with curly hair and keen blue eyes, who was like the man in the fairy tale, and did not know how to shiver and shake.

One day as Gordon was going the round of the trenches he heard a corporal and a sapper having hot words. He stopped and asked what the quarrel was about, and was told that the men were putting fresh gabions (baskets full of earth behind which they sheltered from the fire of the enemy's guns) in the battery. The corporal had ordered the sapper to stand up on a parapet where the fire from the guns would hail upon him, while he himself, in safety down below, handed the baskets up to him. In one moment Gordon had jumped up on to the parapet, and ordered the corporal to stand beside him while the sapper handed up baskets to them. The Russian bullets pattered around them as they worked, but they finished their work in safety. When it was done, Gordon turned to the corporal and said: "Never order a man to do anything that you are afraid to do yourself."

On 6th June there was a great duel between the guns of the Russians and those of their besiegers. A stone from a round shot struck Gordon, and stunned him for some time, and he was reported "Wounded" by the surgeon, greatly to his disgust. All day and all night, and until four o'clock next day, the firing went on. At four o'clock on the second day the English and their allies began to fire from new batteries. A thousand guns kept up a steady, terrible fire of shells, and, protected by the fire, the French dashed forward and seized one of the Russians' most important positions. Attacking and being driven back, attacking again and gaining some ground, once more attacking and losing what they had gained, leaving men lying dead and dying where the fight had been fiercest, so the weary days and nights dragged past.

"Charlie is all right," his brother wrote home, "and has escaped amidst a terrific shower of grape and shells of every description.… He is now fast asleep in his tent, having been in the trenches from two o'clock yesterday morning during the cannonade until seven last night, and again from 12-30 this morning until noon."

Both sides agreed to stop fighting for a few days after this, in order to bury the dead.

The whole ground before Sebastopol was, Gordon wrote, "one great graveyard of men, freshly made mounds of dark earth covering English, French, and Russians."

From this time until September the war dragged on. It was a dull and dreary time, and as September drew near Gordon thought of happy days in England, with the scent of autumn leaves, and the whir of a covey of birds rising from the stubble, and he longed for partridge-shooting. But they shot men, not birds, in the Crimea. "The Russians are brave," he wrote, "certainly inferior to none; their work is stupendous, their shell practice is beautiful." Gordon was never one to grudge praise to his enemies.

Every day men died of disease, or were killed or wounded. On 31st August 1855, Gordon wrote that "Captain Wolseley (90th Regiment), an assistant engineer, has been wounded by a stone." In spite of stones and shells, Captain Wolseley fought many brave fights, and years afterwards became Lord Wolseley, Commander-in-Chief of the British Army, a gallant soldier and a brilliant leader of men.

On 8th September one of the chief holds of the Russians was stormed by the French, who took it after a fierce fight and hoisted on it their flag. This was the signal for the English to attack the great fort of the Redan. With a rush they got to the ditch between them and the fortress, put up their ladders, and entered it. For half-an-hour they held it nobly. Then enormous numbers of fresh Russian troops came to the attack, and our men were driven out with terrible loss. At the same time, at another point, the French were driven back. Nothing was left for the allied troops but to wait till morning. It was decided that when morning came the Highland soldiers must storm and take the Redan. But this the Russians gave them no chance to do.

While Gordon was on duty in the trenches that night he heard a terrific explosion.
