January 19 The Battle of the Paracel Islands is an engagement fought between the naval forces of the People’s Republic of China (PRC) and the RVN (Republic of Vietnam/South Vietnam) in the Paracel Islands. The battle is an attempt by the South Vietnamese navy to expel the Chinese navy from the area. As a result of the battle, the PRC established de facto control over the Paracels. After the reunification of Vietnam in April 1975, the Socialist Republic of Vietnam publicly renewed its claim to the Paracels, and the dispute continues to this day. Hanoi has praised the South Vietnamese forces that took part in the battle.

July 30 The House Judiciary Committee recommends impeaching Nixon on 3 counts; count 1: obstruction of justice; count 2 abuse of power; count 3: contempt of Congress. Omitted is the article introduced by Michigan Congressman, John Conyers charging that Nixon had intentionally concealed from Congress “the facts” and had submitted to Congress “false and misleading statements concerning the existence, scope and nature of American bombing operations in Cambodia” in disregard of Congress’s constitutional power to declare war. Conyers, (number 13 on Nixon’s Enemies List), argued that the president’s desire to cover-up the facts of the bombing campaign was another example of the issue underlying “all of the acts [of presidential wrongdoing] that have been debated thus far.” The article fails to gain widespread support, however, and is defeated 12–26. Nine Democrats, including House Judiciary chair Peter Rodino, along with all 17 Republicans vote against it. While no one challenged the veracity of the allegations contained in the article, it fails, Conyers later observed, because “condemning the Cambodian bombing would also have required us to indict previous administrations and to admit that the Congress has failed to fully meet its own constitutional obligations.” Those opposed pointed out that key congressional leaders of both political parties had been privy to the information and had neither said anything to the rest of Congress nor done anything about it, contending that the president’s actions had been appropriate uses of his power as Commander-in-chief, noting that this particular Congressional-authority versus Presidential-authority dispute had already been addressed by the War Powers Resolution (passed over Nixon’s veto one year earlier). Another factor working against the proposal was the realization that putting the Cambodia article before the full House would interject the issue of the Vietnam War into the impeachment debate

PAVN assaults on Nui Ba Den continue throughout December 1974. RVNAF efforts to resupply the troops on Nui Ba Den are largely unsuccessful. Helicopters are driven off by heavy fire, and fighter-bombers are forced to excessive altitudes by SA-7 missiles and antiaircraft artillery. One F-5A fighter-bomber is shot down by an SA-7 on 14 December. On 6 January 1975, without food and water and with nearly all ammunition expended, the company withdraws down the mountain.
