Then maybe Mark needs to change the title of his list... Seriously, am surprised to hear that Dr Brydon was the only survivor of the 44th to get a medal. Would you mind posting more info about your sources? Dr Brydon may have been the only man to have made it to Jellalabad, but there was at least one other survivor of the 44th: Captain Souter.
Other officers may have survived. According to
http://members.tripod.com/Glosters/FAfghan.htm, a memorial erected in Alverstoke Church near Gosport reads
Sacred to the memory of Colonel T. Mackrell, ADC to Her Majesty. Major W.B. Scott, Captain T. Swaine, Captain R.B. McRea, Captain T.R. Leighton, Captain T. Robinson, Captain F.C. Collins, Lieutenant W.H. Dodgin, Lieutenant W.G. White, Lieutenant W.G. Wade, Lieutenant H. Cadett, Lieutenant S. Swinton, Lieutenant F.J.C. Fortye, Lieutenant A.W. Gray, Paymaster T. Bourke, Lieut. and Qr. Master R.B. Halahan, Surgeon J. Harcourt, Assistant Surgeon W. Balfour, Assistant Surgeon W. Primrose. And 645 non-commissioned officers and soldiers of the 44th Regiment, who fell upon the field of battle in the disastrous Affghan War of 1841 and 1842. They sank with arms in their hands unconquered, but overpowered by the united horrors of climate, treachery, and barbarous warefare; their colours saved by Captain J. Souter, one of the few survivors, hang above this stone, which is erected to their memory by the officers of the 44th Regiment, June 1844.
Some enlisted men of the 44th may also have survived. According to Lady Sale's journal, which was published in 1843, six men of the 44th were captured on 10 January 1842 in the company of Mr Magrath, a surgeon of the 37th NI; up to eight men of the 44th or artillery survived the 'last stand' at Gundamuk on 13 January 1842 and were captured along with Captain Souter.

Note: There is a story that, of the two colours carried by the 44th, the Queen's Colour was lost and only the Regimental Colour was saved by Souter and made it back to England. Can anybody out there confirm or deny this story? Please post the details on this forum!
