The Boer War coming as it did at the end of the 19th Century coincided with major changes in the stark social differences between the officer class and the other ranks of Victoria's army. I recently acquired a book(see below) that has a well-referenced section describing the differences between the "Officers and Gentlemen" and the "Other Ranks" during the 19th Century. The officers led an ivory tower existence and "relied on the noncommissioned officers for a great deal of the leadership and management of the troops". Also while "junior officers cavorted, senior officers spent their time .... intriguing and calculating their chances of promotion."
Colonel Park was a product of his time. In his letters to his wife, he reveals how much his life in India and his prospects for promotion meant to him. He shows concern for the health of his officers, but there is little or no mention of the other ranks.
The situation in Colonial regiments was very different. For example, the officers and men of Natal's volunteer regiments were often friends and neighbours. Those in the regional squadrons of the Natal Carbineers and Border Mounted Rifles included a large number of farmers, so, while some may have been higher born than others, there was nothing to match the class differences evident in the Imperial army. The contempt that Colonel Park clearly felt for Colonial soldiers was based on no more than prejudice.
