"But what Charles Gordon considered as his greatest achievement was one that he in after years often alluded to. At this time (1848) the senior class of Cadets, then called the Practical Class, were located in the Royal Arsenal, and in front of their halls of study there were earthworks upon which they were practised from time to time in profiling and other matters. The ins and outs of these works were thoroughly well known to Charles Gordon and his brother, who stole out at night--but we will leave him to tell his own story. He says: 'I forgot to tell----of how when Colonel John Travers of the Hill Folk (he lived on Shooter's Hill) was lecturing to the Arsenal Cadets in the evening, a crash was heard, and every one thought every pane of glass was broken; small shot had been thrown. However, it was a very serious affair, for like the upsetting of a hive, the Cadets came out, and only darkness, speed, and knowledge of the fieldworks thrown up near the lecture-room enabled us to escape. That was before I entered the curriculum. The culprits were known afterwards, and for some time avoided the vicinity of the Cadets. I remember it with horror to this day, for no mercy would have been shown by the Pussies, as the Cadets were called.'" After he entered the Academy the same love of fun and practical joking characterised him. Sir Henry writes: "After he had been some time at the Academy and earned many good-conduct badges, an occasion arose when it became necessary to restrain the Cadets in leaving the dining-hall, the approach to which was by a narrow staircase. At the top of this staircase stood the senior corporal, with outstretched arms, facing the body of Cadets. This was too much for Charlie Gordon, who, putting his head down, butted with it, and catching the officer in the pit of the stomach not only sent him down the stairs, but through the glass door beyond. The officer jumped up unhurt, and Gordon was placed in confinement and nearly dismissed. "Upon another occasion, when he was near his commission, a great deal of bullying was going on, and in order to repress it a number of the last comers were questioned, when one of them said that Charlie Gordon had on one occasion hit him on the head with a clothesbrush. The lad admitted it was not a severe blow; nevertheless Charlie Gordon was for this slight offence put back six months for his commission, which turned out well in the end, since it secured for him a second lieutenancy in the Royal Engineers in place of the Royal Artillery." This alteration in the branch of the service to which he was attached was due to his own act. He decided that, as his contemporaries would be put ahead of him, he would work for the Engineers instead of the Artillery.
