With the outbreak of the 1947-48 Civil War in Mandatory Palestine, Kelman was a senior member of the Palmach. Following the Al-Khisas raid, 18 December 1947, when a woman member of the Palmach refused to throw a grenade into a room in which she could hear a child crying, Kelman argued that women should not be used on front line duties but should be used as "cooks and service people."
1948
On 15 February 1948, Kelman led a force of 60 men which attacked the remote village Sa'sa', in the Upper Galilee. The operation coincided with a number of other attacks on Arab targets. Its intention was to demonstrate that no village was beyond the reach of the Haganah and to restore Jewish public morale following the deaths of 35 members of the Haganah attempting to reach the outpost of Kfar Etzion a month previously. According to the Haganah's official history, the village was a base for Arab fighters. Kelman had orders to "blow up twenty houses and kill the largest possible number of fighters." During the nighttime attack ten houses where destroyed or damaged and "tens" of people killed. Kelman is quoted as saying 35 houses were demolished and 60 - 80 killed. , 1948.

Two or three days later, Kelman ordered the shooting of "70 or so" Arab prisoners in a gully close to Safad, many of them young men taken prisoner at Ein al-Zeitun. Afterwards a female member of the Palmach, Netiva Ben-Yehuda, was ordered, with others, to the untie ropes from the dead when it was feared that the bodies might be discovered by members of the Red Cross who were visiting the area. Ilan Pappe states that one of the reasons for this and "many other mass killings" was that the Haganah did not have facilities for large numbers of prisoners.
