Notes:
1. Earlier in the Shanghai campaign the 1st Air Sentai had an escort of a 30th Tai of 4 destroyers. Formerly Kamoi had an escort of 28th Tai of 4 destroyers also. It is likely they had similar if not the same escorts here.

2. From: [1]
- 5/10 11 Ships and 18 planes bombarded Ho-to and Ao-tou. 20 motor boats landed infantry at Wu-tung.
- 5/11 More landings at Huang-tso and Ta-tao. 3 destroyers and 2 Gunboats attacked the fortress there to cover the landings. This indicates there was at least one Tai of destroyers with this operation.
