Led escort of Guadalcanal troop convoy as flagship of Comdesron 2 (Admiral Tanaka Raizo). Composition: HAYASHIO, AMAGIRI, MOCHIZUKI under Tanaka's direct command; Desdiv 15 OYASHIO (f), KAGERO; Desdiv 24 UMIKAZE (f), KAWAKAZE, SUZUKAZE; and Desdiv 31 TAKANAMI (f), NAGANAMI, MAKINAMI escorting transports NAGARA MARU, HIROKAWA MARU, SADO MARU, CANBERRA MARU, NAKO MARU, YAMAZUKI MARU, YAMAURA MARU, KINUGAWA MARU, SHINANO MARU, BRISBANE MARU, and ARIZONA MARU. Embarked aboard are the HQ and 1st Battalion of the 229th Infantry Regiment, the 2nd Battalion of the 230th Infantry Regiment, various units of 38th Division, eighty-three landing craft, more than 30,000 artillery shells, and supplies for 30,000 men for twenty days.
While heading toward Guadalcanal the morning after the great naval battle and failed bombardment mission of Batdiv 3, the transport force is attacked by wave after wave of American aircraft. It is a disaster: all but five transports are sunk. One, SADO MARU, turns back, and the remaining four were held back by Tanaka as he awaited the results of the coming second naval night battle of Guadalcanal as KIRISHIMA and Kondo's force attempted to complete the bombardment mission.
In the early hours of the morning Kondo's force is intercepted by an American battleship squadron [WASHINGTON and SOUTH DAKOTA] and the KIRISHIMA is sunk in the surface battle. However, the Americans suffer heavy destroyer losses and retire and the battleship's sacrifice does end up clearing the path on the surface for Tanaka's waiting transports.
- Predawn: HAYASHIO stood guard with the other destroyers as the surviving four transports - KINUGAWA MARU, YAMAURA MARU, HIROKAWA MARU, YAMAZUKI MARU - stubbornly proceeded to Guadalcanal and are run ashore to successfully make make emergency offloading of 2,000 troops, ammunition, and food. Air attacks later that morning then destroyed the grounded Marus.
- 2040: Returned to the Shortlands. HAYASHIO suffered no damage and the one bright spot for the Japanese was the comparatively small loss of life - 450 troops killed in the air attacks with some 5,000 returned safely to the Shortlands.
0532 Departed; escorted SUZUYA, MAYA and TENRYU from Shortlands to Kavieng.
18 November 1942:
1242: Arrived at Kavieng. Assigned to patrol duties.
HAYASHIO relieved by minelayer SHIRATAKA at Kavieng so that the destroyer can join the East New Guinea Reinforcement Force operations to make up for losses.
HAYASHIO departed Kavieng for Rabaul.
Arrived at Rabaul. Immediately prepares for sortie for transport run.
- 2100 Transport run under Comdesdiv 2 Captain Tachibana Masao departs Rabaul to re-supply and re-inforce Lae/Salamua: (F) HARUSAME, SHIRATSUYU, INAZUMA, HAYASHIO, and ISONAMI. As they enter the area of likely attack speed is increased to 30 knots.
24 November 1942:
- 1853 Attacked by B-17 bombing out of the moonlight. Near-missed forward and amidships by three bombs to port and one to starboard. The port engine goes offline but HAYASHIO is able to withdraw at 28 knots using her starboard engine.
- 2100 A single B-17 flying at low level again bombs the destroyer at a point 67 degrees 35 miles from Salamua. This time in addition to near-misses around the bow HAYASHIO received a direct hit on the port side of the forward turret incapacitating the mount. More troublesome are fires are started in both boats flanking the bridge. The blaze proves to be stubborn and spreads, endangering the bombardment munitions in the forecastle she is carrying. There were many killed and wounded by the bomb detonations and fires. The main and secondary batterys were rendered useless. The fire threatens to set off the destroyer's torpedoes. The destroyer halts and anchors in Guna Bay, Huon Gulf to attempt to fight the fires. This fails, and the forward magazines explode inside the hour, reducing HAYASHIO to a wreck. But she remains afloat.
- 2225 Commander Kaneda orders Abandon Ship, and all transfer to the SHIRATSUYU now standing by. At 2235 HAYASHIO suffers another major induced explosion as some of her torpedoes exploded, and it is decided she should be sunk. SHIRATSUYU opens 5" inch gunfire, and at 2305 HAYASHIO's hulk sinks. Three officers and forty-seven petty officers and men are lost, but the others including Commander Kaneda (to C.O. NIIZUKI) and six badly wounded, are rescued. (It is not stated how many of the lost were soldiers).
- Though the squadron is close to its destination by now, Captain Tachibana judges the danger too great, and calls off the mission. The ships return to Rabaul.
25 November 1942:
- 0200 INAZUMA sends word she has HAYASHIO's survivors now aboard and is returning. 
- 1750 The other destroyers arrived back at Rabaul.
24 December 1942:
Removed from Navy List.
 The B-17's were of seven aircraft of the 63rd Heavy Bomb Squadron loaded with twenty 100 lbs. and 150 lbs. fragmentation bombs, bombing from 2,000 feet. The B-17 that claimed the direct hit was # 41-24521.
 This is not specifically mentioned in most accounts of HAYASHIO's loss and the message is the only source, but the Tokyo Express run in question itself is generally neglected. Given the small size of SHIRATSUYU and the large number of HAYASHIO survivors, it is not unlikely they were transferred to the larger INAZUMA for the trip back to port. A similar transfer event happened with large numbers of rescued by INAZUMA in Java Sea operations - in this case Allied survivors.
