SECTION II - PREPARATION FOR THE EXPEDITION

The Corps

Divide the class into teams and assign students a Corps member (of the permanent party) to become an “expert” on.  Each student should make a list of the skills and other attributes of the Corps member they research.  They should know as much about their assigned Corps member as possible.

Present the following scenarios to the teams.  The experts should relay their information to their team members with the team deciding how and by whom the situation should be handled.  Have all the teams report their decisions.

Scenarios:
 
  • Grizzly Bear comes into Camp looking for food
  • Buffalo stampede into the River as the Corps is traveling in the same direction
  • Blackfeet Indians attempt to steal the Corps supplies and horses
  • As the Corps comes ashore they are met by hundreds of Native Americans lined along the river bank
  • Seaman has been captured by the Walla Walla tribe
  • A Native Indian boy has been found along the river bank, is barely breathing and appears to have been wounded by an animal
  • As the winter progresses, hunting does not providing meat for the explorers

Examine the document of the medical supplies purchased for the expedition and Dr. Rush's letter of instruction to Meriwether Lewis on preserving his health.  In the chart below record your research findings on what medical situations these items might have been used for.  In the 2003 Column, list what modern medicines or instruments have replaced the 1803 medical supplies.

Explorations of the West

Thomas Jefferson was intensely interested in westward exploration.  He had studied and promoted Western Exploration (see articles one and two).   Match these exploration dates with the explorers (printer friendly version):

List of Dates:  

1753
1783
1786
1793
July 22, 1793
1803-1806
1805
1806  

Explorers:

  • Andre Michaux, French botanist, sponsored by Jefferson and the American Philosophical Society, to explore a route to the Pacific Ocean.  Mission abandoned.
  • Rogers Clark (brother of William Clark) asked by Jefferson to explore the westward lands.  Clark declines.
  • Lieutenant Zebulon Pike explores the headwaters of the Mississippi River.
  • John Ledyard (American) plans to cross Russia to reach the North American Coast to explore the Pacific lands.  Catherine the Great has him arrested and escorted out of Russia.
  • Alexander MacKenzie (Scottish Canadian) reaches the Pacific Ocean by a land route from Canada.
  • Thomas Walker and the Loyal Company plan to explore the Missouri River.  Project is abandoned.
  • Meriwether Lewis and William Clark with instructions from Jefferson explore the westward lands.
  • Captain Zebulon Pike explores the Red River and Arkansas River.  Arrested by the Spanish.  

In 1802 Jefferson gets a copy of Alexander MacKenzie’s published journal, “Voyages from Montreal on the River St. Lawrence Through the Continent of North America to the Frozen and Pacific Oceans In the Year 1789 and 1793.” 

Using the image of MacKenzie at right and the map from MacKenzie’s journal, assign students the task of promoting/marketing the sale of MacKenzie book. Students should consider:  

  • creating a broadside/poster/flyer

  • giving the book a more appealing title

  • writing an ad

  • giving a press conference

  • hosting a book signing

When MacKenzie reached the Pacific Ocean he used vermilion paint and grease to leave his “mark” on rocks.  Ask students to compose the “mark” they would use if they had the opportunity to make a discovery.  The Corps of Discovery would also make "marks" on trees when they reached the Pacific. Unfortunately none of those "marks" exist today. Can you explain why?

How many years after MacKenzie would it be before Lewis and Clark reached the Pacific Ocean?

Compare and contrast the MacKenzie map with the Lewis and Clark map (note: these are large files).  What similarities do you see?  Any differences? 

Training

The following individuals provided training to Lewis in preparation for the journey.  Have students research these individuals. Based on their research have the students complete the chart below.

What skills did Lewis already have that led Jefferson to choose him to lead the expedition?

Clark took his slave York along on the expedition.  Using the image of York write a newspaper account of York and the Arikara Indians.

What jobs do you think York provided to Clark as a slave?  What contributions do you think York made to the expedition as a member of the Corps of Discovery?  Create a chart of these jobs/contributions.  What generalizations can you make about York’s role as a member of the Corps of Discovery?

On January 15, 1807 Lewis sent his roll of men to the Secretary of War, writing:

“With rispect to all those persons whose names are entered on this roll, I feel a peculiar pleasure in declaring, that the Amble support which they gave me under every difficulty; the manly firmness which they evinced on every necessary occasion; and the patience and fortitude with which they submited to, and bore, the fatigues and painful sufferings incident to my late tour of the Pacific Ocean, entitles them to my warmest approbation and thanks; nor will I suppress the expression of a hope, that the recollection of services thus faithfully performed will meet a just reward in an ample renumeration on the party of our Government.”

Based on York’s role as a member of the Corps, what would be your recommendation of a reward for York for the successful expedition of the Corps?   What were the rewards bestowed upon Captain Lewis and Captain Clark at the journey’s successful completion? Use the chart below (printer friendly version) to record your findings.
