Hello Fabrizio and de Domenico,

I am not sure if the following is the same action when VAS 234 was destroyed but here it is:
At 1345/9 September the minelayers BRANDENBURG and POMMERN sailed from Leghorn to round up Italian steamers. Almost immediately the patrol-boat D.1 was stopped and ordered to Leghorn then an auxiliary was sighted going south (this was PIERO FOSCARI, flying a Rear-Admiral Flag, do you know who it was?), a warning shot was fire at 10,400 meters but the vessel kept on going and POMMERN now opened fire forcing the vessel ashore where she was abandoned (and sunk the next day by BRANDENBURG). In the meanwhile BRANDENBURG had sighted several small vessels to the North and turned toward them. Two of these were MTBs and one of them kept on coming at high speed toward BRANDENBURG and the German warship opened fire with a 3.7 cm gun but fired in front of the the MTB hoping it would turn away but it kept on coming and at 1531 general fire was opened with light guns (the 10.5 cm guns were not used) and the boat apparently had a direct hit and turned away, fire was checked at 1532. The two MTBs now withdrew to the West.
Six R-boats had been sent on patrol earlier in the day but I do not have any information on what they did.
The same evening BRANDENBURG, POMMERN, SG.11 and five R-boats of the 11th Flotilla (R.189, R.199, R.201, R.212 and R.215) and two R-boats of 6th Flotilla (R.12 and R.15) sailed for Toulon but shortly after were recalled. If two R-boats were indeed involved then it was probably from this group and one would have to check the KTBs of these two flotillas.

Best regards,

Platon
