Unit dispositions along the line had changed little since General Walker succeeded in manning it.
The 8213th Army Unit patrolled Kanghwa Island at the extreme west in the I Corps sector.
Next east, the Turkish Brigade overlooked the Han River estuary from the upper end of the Kimpo peninsula.
Above the Han, the 25th Infantry Division, to which the Turks and Rangers were attached, straddled Route 1 along the lower bank of the Imjin River, and the ROK 1st Division defended the Corps' right from positions along the Imjin reaching northeast almost to Route 33 in the Wonsan-Seoul corridor.
The British 29th Brigade was assembled in I Corps reserve along Route 1 just outside Seoul.
IX Corps lay across the Wonsan-Seoul corridor along the 38th parallel, the ROK 6th Division astride Route 33 at the left, the 24th Division across Route 3 at the right.
In Corps' reserve, the British 27th Brigade was assembled near the junction of Routes 33 and 3 at Uijongbu.
The 1st Cavalry Division, also in reserve, retained the mission assigned to it while under army control of blocking the Ch’unch’on-Seoul road.
Now attached to the cavalry division were the Filipino battalion and the Greek Expeditionary Force, an infantry battalion that had reached Korea on 8 December.
Near the 38th Parallel above Ch’unch’on, ROK III Corps defended a wide sector with the ROK 2nd, 5th and 8th Divisions on line and the ROK 7th Division in reserve.
In the narrow ROK II Corps sector next east, a single division, the ROK 3rd, continued to block Route 24 running southwestward through the Hongch’on River valley.
ROK I Corps defended a gaping line at the Eighth Army right, with the ROK 9th Division in the high mountains at the Corps' left and the ROK Capital Division across the slopes and coastal road at the eastern anchor of the front.
Ridgway's main reserve for strengthening the front was X Corps.
Other resources present or scheduled to arrive in Korea by the end of the year were exceedingly few.
The US 2nd Infantry Division, still not fully recovered from its late November losses but now reinforced by the Netherlands and French battalions, was centrally located at Ch’ungju.
In the west, the 187th Airborne Regimental Combat Team, with the Thai battalion attached, was assembled at Suwon south of Seoul.
Outside these forces, the only available unit was the ROK 11th Division currently operating against guerrillas in various locations to the south.
The 2nd Battalion of Canada's Princess Patricia's Light Infantry had reached Korea in mid-December but was at Miryang in the southeast for eight weeks of training before entering battle.
Similarly, the 16th New Zealand Field Regiment, actually an artillery battalion, due to reach Korea on the 31st, would require training before it moved to the front.
The only units en route to Korea that might be able to move forward upon arrival were two US airborne Ranger companies, the 2nd and 4th.

Holding against the threatening enemy offensive, Ridgway judged, rested on committing most of his reserves early and on revitalizing the spirit of the Eighth Army.
By the time he returned to Taegu on the 30th he had taken several steps toward achieving both.
Restoring the Eighth Army's morale and confidence, Ridgway believed, depended mainly on improving leadership throughout his command, but before he would relieve any commander, he wanted personally to see more of the man in action, to know that the relief would not damage the unit involved, and to be sure that he had a better commander available.
For the time being, he intended to correct deficiencies by working “on and through” his current Corps and division commanders.
One deficiency he had noted was that many commanders conducted operations from command posts far behind the front.
To correct this practice, he ordered "division commanders to be up with their forward battalions, and... corps commanders up with the regiment that was in the hottest action."
He saw further weaknesses in leadership and staff work in the intelligence briefings he received.
