[486] Based on compilation on 15 March 1951 by Casualty Reporting Officer.
[487] Based on G-2 Report included in the Special Action Report for the Inchon-Seoul Campaign. The figures shown are less than the total of regimental reports of captures, as only those POWs remaining after processing by the G-2 were counted. Oftentimes civilians were turned over to the G-2 as POWs. A lag is also reflected in the figures of the G-2 Section. Both regiments captured prisoners on D-Day, 15 September, but the prisoners were not processed until 16 September.
[488] Estimated enemy casualties do not include POWs. Figures shown are based on the G-2 Report included in the Special Action Report for the Inchon-Seoul Campaign.
[489] The figure shown for 16 September includes the casualties inflicted on the enemy on 15 September.
