802. My 755.2 Department has cabled in substance as follows: “Four O-boats might replace 4-K’s3 before lapse of three months but before deciding Department desires further particulars as to condition of boats, whether their condition is different from condition when they left United States, and wherein they have proved unsuccessful for operating.

     I have replied stating that I consider boats in as good condition now as when they left United States, but owing to constant necessity for repairs with limited facilities at Azores I recommended new boats be sent.4 Also informed Department your written reports did not indicate serious inability on the part of the boats to operate against enemy. 22207. 802.
