What does this second request add that is not already included in the previous listed request of עשה למען הרוגים על שם קדשך? They seem to say the same general concept regarding those that died for the sake of sanctifying the Name of G-d. Why the need to say the request twice?
However, we can distinguish between the two requests, with the understanding that the second request adds to the first request.
The word הרג indicates the killing of a individual, for example, הלהרגני אתה אומר (שמות ב,יד), and many other places. In contrast, the term טבח indicates spilling the blood of a crowd. Thus, the latter term indicates a wider and more dreaded form of killing.
Thus, in our requests, we say if it is not enough to be answered for the sake of individuals that were killed, then our request should be answered for the sake those killed in large groups (such as the 10 Martyrs).
