The Battles of Bir 'Asluj refer to a series of military engagements between Israel and Egypt in the 1948 Arab–Israeli War, around the localities Bir 'Asluj and the nearby Bir Thamila (also Bir Tamila or Bir Tmileh). Bir 'Asluj was a small Bedouin center and a strategic location on the 'Auja–Beersheba road. The Israelis captured the position early in the war, in an attempt to disconnect the Egyptian Muslim Brotherhood forces from the main Egyptian Army concentration on the coastal plain, but set up positions across the road and the threat to their transport was neutralized.
The entire vicinity of Bir 'Asluj, including Bir Thamila, was captured by Israeli Negev Brigade forces on December 25–26, 1948, during Operation Horev. In the first stage, the 7th Battalion took Bir Thamila, but failed to reach the road and retreated with heavy losses. In the morning, armored vehicles from the 9th Battalion assaulted the Egyptian road positions and captured them. This was later followed by the conquest of the entire road to the border at 'Auja, expelling the Egyptian forces from Israel in this region.
