Focus window: 110 September 1944 Source PDFs covered: Calgary Highlanders, 5 Cdn Inf Bde, RHC Black Watch (R de Mais inventory not provided) Inventory coverage: CH pp. 145 of 343 · 5 CIB pp. 156 of 193 · BW pp. 151 of 144 Document count: 24 items Status: Ready for use; gaps flagged at end


Selection criteria (priority order)

  1. Documents covering specific events the Calgary Highlanders were involved in during 110 Sep 1944
  2. Brigade-level signals, sitreps, or orders covering the same dates and actions
  3. Sister-battalion entries that mention or coordinate with the Calgary Highlanders during the focus window
  4. Patrol programmes, patrol reports, casualty returns, or other operational documents adding detail beyond the diary narrative

Source 1 — Calgary Highlanders War Diary

File: Calgary-Highlanders_War-Diary_Sep44.pdf (343 pp; inventoried 145)

Page(s) Document type Date covered Note

2126 War diary narrative pp. 1520 1113 Sep 44 Just outside window — direct continuation of Loon Plage fighting Bloggins entered 710 Sep; drop if hard 10 Sep cut required

Source 2 — 5 Cdn Inf Bde War Diary

Page(s) Document type Date covered Note

2834 AFW 3008 Field Returns of Officers (Appx 3) wks ending 2 & 9 Sep 44 Officer strength returns spanning focus window — establishes who was commanding what when Bloggins arrived
3543 AFW 3009 Field Returns of Other Ranks (Appx 4) wks ending 2 & 9 Sep 44 OR strength returns — directly relevant to Bloggins as reinforcement; bde-level intake picture in his first days

4849 Mov Order No 6 5 Sep 44 Mid-window move order covering advance toward Dunkerque outpost line

Source 3 — RHC Black Watch War Diary

File: RHC-Blackwatch_War-Diary_Sep44.pdf (144 pp; inventoried 151)

Page(s) Document type Date covered Note
615 Bn war diary narrative (Lt-Col Ritchie) 130 Sep 44 Sister-bn narrative; only 110 Sep entries in scope. BW alongside CH through Dieppe parade (3 Sep) and advance to Dunkerque approaches
18 SHAEF "Enemy Defences" trace 23 Aug 44 Pre-window but describes enemy defences CH would encounter at Bourbourgville/Loon Plage from 7 Sep — operational intel context
19 Dunkerque Plan of Port & Town n/d Terrain CH was advancing toward through focus window
20 Dunkerque defence overprint map Ed. 11 Sep 44 Compiled from air photo info as at 1 Sep and other sources as at 10 Sep — situation across Bloggins's first ten days
21 Defence overprint legend n/d Companion key to the overprint — needed to read p. 20
2425 RHC Field Return of Officers wk ending 2 Sep 44 Sister-bn officer strength at start of window
2627 RHC Field Return of Officers wk ending 9 Sep 44 Sister-bn officer strength at close of window
33 Field Message Form (Lt-Col Ritchie to coys) 10 Sep 44, 0025 hrs Only timed BW signal in window — H-hour change to 0755, RV at 853093 at 0700; bde-sector operational tempo on closing night

Items considered and excluded

Source Page(s) Reason for exclusion
BW 2223, 2829, 3031 Officer returns wks ending 16, 23, 30 Sep — outside window
BW 3839, 4041, 4244 OR returns wks ending 16, 23, 30 Sep — outside window
BW 4649 Undated coy messages and faded carbon — cannot place in window with confidence
5 CIB 5356 Mov Orders 9 (17 Sep) and later — outside window

Gaps — material expected but not in catalogued ranges

  1. R de Mais war diary inventory — not provided. Largest gap. R de Mais was the third bn in 5 CIB, operating alongside CH throughout focus window. Without it, criterion 3 (sister-bn coordination) is half-answered.

  2. Calgary Highlanders Appendices 315 — none catalogued. The CH Move Orders (Appx 4), Messages (Appx 5), Patrol Programme (Appx 6), Memorial Service 3 Sep (Appx 12), and March Past Dieppe (Appx 13) are all directly in scope and almost certainly the highest-value supplementary documents in the entire source set. Inventorying CH pp. 46343 should be the next priority.

  3. 5 CIB Ops Log (Appx 13, sheets 109161) — un-catalogued in pp. 57193. Bde signal log for the whole month; would be the single richest source of bde-level granularity for 110 Sep.

  4. 5 CIB Patrol Programmes and Patrol Reports (Appx 6, 7) — un-catalogued. Patrol activity at Loon Plage from 910 Sep described in CH narrative; patrol reports would corroborate.

  5. 5 CIB Int Report on Dunkerque, 13 Sep (Appx 10) — outside date but retrospective on focus-window area; un-catalogued.

  6. BW Appx 6 (Warning Orders, movement tables) and Appx 8 (Sitreps) — un-catalogued in pp. 52144. Sitreps would map well onto focus window.

  7. No casualty returns in any catalogued range. CH narrative refers to casualties 710 Sep at Bourbourgville/Loon Plage; actual casualty returns (Part II Orders, AFW 3010-series, or unit casualty lists) aren't in catalogued portions of any file. Likely in CH Appx 2 (Part II Orders) or BW Appx 2 ("to follow").

  8. No artillery task tables in scope. CH Appx 3 (Arty Task Tables) and BW Appx 7 (RCA Conc tables, tasks) both un-catalogued and would directly cover fire support for actions Bloggins was in.


To meaningfully increase supplementary-source density:

  • CH pp. 46100 — capture early appendices likely covering 110 Sep (Move Orders, Messages, Patrol Programme, Memorial Service, Dieppe March Past)
  • 5 CIB pp. 57100 — find start of Ops Log (Appx 13) and patrol material (Appx 6, 7)
  • R de Mais Sep 44 war diary — full inventory pp. 1~50 to recover sister-bn coordination evidence

These three passes would roughly double the supplementary-source density of this list.
