On July 18, 1963 Nasserist officers under Jassem Alwan, with Egyptian intelligence support, launched a daytime assault on the army headquarters and radio station in Damascus, seeking to overturn the Baathist regime installed on March 8. The attack failed after fierce fighting that left hundreds dead, with Amin al-Hafiz personally directing the defense of army headquarters. The regime broke precedent by executing 27 participants after summary proceedings, where exile or imprisonment had been the Syrian norm for failed coups.
NCRC chairman and head of state Lieutenant General Luay al-Atassi opposed the executions and challenged the death sentences passed on Alwan and his co-leaders, but was overruled by the Baathist majority aligned with al-Hafiz, who advocated carrying them out; al-Atassi, already suspected by the Military Committee of Nasserist sympathies, resigned in protest. On July 27, 1963 Amin al-Hafiz replaced him as president of the NCRC and head of state, completing the Military Committee faction's consolidation.

Sources
On 18 July the Nasserists under Jassem Alwan, helped by Egyptian intelligence, attempted a daytime coup, attacking the army headquarters, personally defended by al-Hafiz, and the broadcast station; the battle left hundreds dead, the attempt failed, 27 participating officers were arrested and executed, a rare punitive action where the typical Syrian punishment had been exile, imprisonment, or a foreign posting, and President Luay al-Atassi subsequently resigned, signalling his disapproval of the executions.
The military court sentenced the three coup leaders Jassem Alwan, Raef al-Maarri, and Mohammed Nabhan to death and passed the decision to the NCRC for final approval; Luay al-Atassi, then NCRC chairman, challenged the sentence, but most of the other Baathists supported the position of the future chairman Amin al-Hafiz, who advocated carrying out the executions, with Atassi handicapped by the Military Committee's suspicions of his sympathies.

Amin al-Hafiz served as president of Syria from 27 July 1963, as president of the National Council of the Revolutionary Command, the country's supreme organ after the March 8 coup, until his overthrow by the Jadid faction on 23 February 1966.
Upon the Baath Party's arrival in power in 1963 the Revolutionary Command Council appointed officer Luay al-Atassi to the council presidency, and after the July uprising Amin al-Hafez became president of the council, holding the post until the 1966 movement brought Nureddin al-Atassi to the head of state.

Editorial Note
Coding note: the dataset's dissident coup on July 27 is the intra regime removal of Luay al-Atassi by the al-Hafiz and Military Committee faction, formalized as a resignation; it should not be confused with the failed July 18 Nasserist rising that precipitated it, which the dataset would carry separately as an unsuccessful attempt. The executions of July 1963 are documented facts reported without editorializing; the death sentences on the three leaders were not carried out immediately and the men were released about a year later at the urging of Nasser and Iraqi president Arif, per the account fetched in batch 13. Arc forward: al-Hafiz fell to Salah Jadid's coup of February 23, 1966.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: Lieutenant General Luay al-Atassi, NCRC chairman and head of state, forced out in the aftermath of the failed July 18 rising; he resigned over the executions of the Nasserist plotters and was not physically harmed. Amin al-Hafiz succeeded him on July 27, 1963..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; not physically harmed. The baseline file does not name individual targets; researched names are kept in a separate layer.
