Captain had been broken in and trained for an army horse; his first owner was an officer of cavalry going out to the Crimean war. He said he quite enjoyed the training with all the other horses, trotting together, turning together, to the right hand or the left, halting at the word of command, or dashing forward at full speed at the sound of the trumpet or signal of the officer.
These shoes will be more comfortable after I have broken them in.
