The corps suffered casualties on many occasions. They had the ill-fortune to be part of the column of Major Paris, and under Lord Methuen, when that General was defeated by Delarey on 7th March 1902. The approximate losses were 4 killed and 4 wounded out of a strength of 64.
From the nominal roll it is possible to determine the enrolment at the end of each month:
This shows that Cullinan's Horse reached their peak embodiment at the end of February 1902 and that many more than 64 men were potentially able to participate in the engagement at Tweebosch a week later.
