Notable events involving Kos XIX include:

5 Nov 1941
The A/S whaler HMS KOS XIX / Cocker (Lt. L.H. Davies, RNR) sighted a periscope about 32 nautical miles west of Alexandria at 2220/5.

A hunt was started and she was joined by the corvette HMS Snapdragon (T/Lt. P.H. Potter, RNR), A/S whaler HMS Falk (Lt. H.S. Upperton, RNR) and the A/S motor boat HMS MA/SB 2.

Destroyer HMS Encounter (Lt.Cdr. E.V.St J. Morgan, RN) was sent from Alexandria to assist. She already sailed at 2325/5.

Two more destroyers, HMS Hotspur (Lt. T.D. Herrick, DSC, RN) and HMS Decoy (Lt.Cdr. J.M. Alliston, RN), joined in the morning 6th. They had sailed at 0900/6 and 1000/6 respectively.

The destroyers were recalled to harbour at 1800 and arrived later in the evening. No contact had been obtained.

As an oil slick was sighted in the area of the hunt on the 7th the destroyers HMS Hotspur and HMS Kipling (Cdr. A. St.Clair-Ford, RN) were sent to hunt in the area again. They departed Alexandria at 1200 and 1400 hours respectively.

The search continued during the night of 7/8 November. HMS Encounter joined the destroyers in the morning. She sailed from Alexandria at 0815/8.

The hunt was however soon abandoned as no contact could be obtained and and the three destroyers then escorted the light cruiser HMS Neptune (Capt. R.C. O'Conor, RN) during a practice bombardment at Aboukir. HMS Neptune had departed Alexandria at 1000/8.

Following the exercise HMS Neptune immediately returned to Alexandria arriving at 1630/8.

HMS Encounter, HMS Hotspur and HMS Kipling returned to Alexandria at 1015/9 having remained outside on patrol for another night. (1)
