Ibn Ishaq wrote the Sirat Rasul Allah and the original of that work no longer exists.
Apparently Ishaq provided an unvarnished view of Mohammad and early Islamic practices and history. Those original works were edited by Ibn Hisham (and translated by Guillaume) who censored Ishaq in an early form of "political correctness." For example, Hisham states that he intentionally omitted portions that did not address Mohammad and "about which the Quran says nothing, ..., things which are disgraceful to discuss; matters which would distress certain people; and such reports as al-Bakka'a told me he could not accept as trustworthy (p. 691). Hisham's censorship appears consistent with Sharia law practices and rulings which may be found in "Reliance of the Traveller: A Classic Manual of Islamic Sacred Law", Book R (Holding One's Tongue), Chapter 2, (Slander), Section 2; and 6, Chapter 23 (Asking About Another's Mistakes) Section 1; Chapter 8 (Lying) Section 2: Chapter 10, (Giving A Misleading Impression) Section 1; Chapter 20, (Picking Apart Another's Words), Section 2 (Giving a Positive Interpretation to Others Seeming Mistakes).; Chapter 24, (Searching Out A Person's Faults); Chapter 36, (Revealing a Secret) Section 1.
However, according to the publishers, in this translation, Guillaume also incorporated a number of additions and variants found in the writings of early authors and what we have, according to the publishers, "may represent in English most of what is known of the life of" Mohammad.
The book is divided into three parts. Part 1 is The Genealogy of Muhammad; Traditions from the Pre-Islamic Era; Muhammad's Childhood and Early Manhood. Part 2 is Muhammad's Call and Preaching in Mecca. Part 3 is Muhammad's Migration to Medina, His Wars, Triumph, and Death.
Part 3 is relevant to the modern researcher in that it contains a comprehensive list of attacks against Non Muslims. These attacks are the result of Mohammad's contention that Allah ordered him to fight non-Muslims and the background for that "revelation" begins on page 212 (Allah orders Muhammad to Fight.)
The lists of attacks, about 45 or so, and a couple of defensive operations, are identified:

Ishaq gives "A Summary of Muhammad's raids and expeditions" (p. 659) recounting that Muhammad personally led 27 raids and actually fought in nine (9) engagements: Badr; Uhud, al-Kandaq; Qurayza; al-Mustaliq; Khubar; the occupation; Hunayn and al-Ta-if.. (p. 660).
Ishaq provides details identifying names of both Muslims and Non-Muslims in multiple engagements, sequencing and phasing of the fighting characterizing various attacks, description, background and narratives of specifically targeted assassination raids, and of the murders of other raid and expedition survivors. For example, the attack on B.Fazara resulted in the capture of Umm Qirfa Fatima d. Rabi'a b. Badr. "She was a very old woman, wife of Malik." And she was murdered "by putting a rope to her two legs and to two camels and driving until they rent her in two (p. 665). Muhammad's piecemeal, leisurely, butchery of between 600 - 900 survivors of the raid on B. Qurayza is described on page 464 and the parceling of the Qurayza property, women and (36) horses among the Muslims is described on page 466.
Contained in each of these descriptions are examples of the planning, execution, discipline and tactics that should be of interest to modern day analysts who are confronted by actors modeling themselves on the examples of Mohammad and his followers.
Whether one is evaluating Mohammad as a self proclaimed prophet, military or diplomatic leader, this particular book is an essential source for analysts and researchers who need the best practical historical record.
