also

begun

the

process

of

building

up

to

four

new

nuclear

at

the

site

of

its

but

in

October

the

Province

of

Ontario

declared

that

the

Darlington

new

citing

the

high

capital

cost

estimates

and

energy

surplus

in

the

province

at

the

time

of

the

announcement

Pickering

proud

of

its

Controversies

and

criticism

Prior

to

shutting

down

its

coal

fueled

generating

stations

OPG

attracted

considerable

controversy

for

the

operation

of

coalfired

generating

stations

which

ranked

among

Canadas

largest

individual

air

pollution

sources

This

was

mostly

because

Nanticoke

housed

a

massive

MW

of

generation

capacity

in

one

site

it

produced

the

most

pollution

in

one

site

despite

being

a

reasonably

clean

plant

per

megawatt

of

power

Nanticoke

Generating

Station

was

North

Americas

largest

coalfired

generating

station

and

the

single

largest

air

pollution

source

for

southern

Ontario

and

northern

New

York

state

attracting

considerable

criticism

from

environmentalists

and

legislators

in

both

jurisdictions

OPGs

Lambton

Generating

Station

was

the

second

largest

air

polluter

in

the

province

The

Liberal

government

of

Dalton

McGuinty

came

to

power

in

with

a

promise

to

phase

out

coal

generation

by

However

for

various

operational

and

demand

reasons

this

was

not

possible

until

when

the

last

coal

was

burned

in

OPGs

stations

The

company

also

endured

significant

criticism

concerning

the

slow

return

to

operation

of

some

of

its

nuclear

generating

stations

which

had

been

shut

down

by

the

North

America

blackout

The

problem

was

that

all

but

one

of

the

reactors

were

tripped

and

allowed

to

poison

out

preventing

an

early

reconnection

to

the

electricity

grid

Once

shut

down

all

nuclear

reactors

take

several

days

to

return

to

service

Another

source

of

criticism

was

the

extended

and

expensive

refit

to

the

reactor

Unit

at

the

Pickering

A

Nuclear

Station

In

late

the

incoming

Liberal

government

fired

the

three

most

senior

executives

at

OPG

on

the

heels

of

a

report

that

the

retrofit

of

a

single

reactor

at

the

Pickering

nuclear

plant

had

come

in

significantly

over

budget

and

three

years

behind

schedule

The

government

also

accepted

the

resignation

of

all

remaining

Board

members

Management

underestimated

the

amount

of

work

and

complexity

of

the

Unit

refurbishment

project

and

failed

to

do

a

complete

scope

analysis

before

starting

Due

to

the

uproar

over

the

large

cost

overruns

and

delays

an

independent

review

committee

was

commissioned

to

examine

the

future

role

of

OPG

in

the

electricity

sector

the

future

structure

of

OPG

the

appropriate

corporate

governance

and

senior

management

structure

and

the

potential

refurbishing

of

Pickering

Units

and

Former

federal

Prime

Minister

John

chaired

the

committee

Peter

Godsoe

Chairman

of

the

Bank

of

Nova

and

Jake

Epp

a

former

federal

Cabinet

Minister

Chair

of

the

Pickering

A

Review

Panel

and

interim

Chairman

of

OPG

also

sat

on

the

committee

The

experience

of

refurbishing

Pickering

A

Unit

was

significantly

different

with

a

much

tighter

adherence

to

schedule

and

budget

Unit

was

returned

to

service

in

November

providing

MW

of

capacity

for

Ontarios

electricity

system

It

was

decided

that

Pickering

Units

and

would

not

be

restarted

as

the

business

case

could

not

be

made

In

early

December

Ontarios

Auditor

General

pointed

out

that

OPG

was

importing

wood

products

from

Europe

to

burn

at

the

Thunder

Bay

station

pushing

the

cost

of

the

electricity

it

generates

to

times

higher

than

other

biomass

generators

or

per

MWh

Subsequently

Ontarios

Development

and

Mines

Minister

Michael

Gravelle

stated

that

OPG

was

seeking

a

local

company

to

produce

the

biomass

fuel

Considering

the

everincreasing

cost

of

electricity

to

Ontario

consumers

the

hiring

of

CEO

Jeffrey

Lyash

in

the

summer

of

created

some

criticism

when

it

was

revealed

that

Lyash

would

earn

per

and

that

could

increase

to

million

with

bonuses

if

and losses 130 killed US body count 1617 killed v t e Military engagements during the Vietnam War Operation Dewey Canyon was the last major offensive by the 3rd Marine Division during the Vietnam War It took place from 22 January through 18 March 1969 and involved a sweep of the Peoples Army of Vietnam PAVNdominated A Shau and Song Đa Krông Valleys by the 9th Marine Regiment Based on intelligence and captured documents the PAVN unit in contact was believed to be the 9th Regiment The 56 days of combat were a tactical success but did not stop the overall flow of North Vietnamese men and matériel into South Vietnam The 9th Marine Regiment and attached units were awarded the Army Presidential Unit Citation for their actions in Operation Dewey Canyon Contents 1 Background 2 Operation 21 Phase 1 22 Phase 2 23 Phase 3 and the raid into Laos 3 Outcome and legacy 4 5 External links Background Throughout 1967 and into 1968 the United States Marine Corps units in the northern I Corps region had been tied to their combat bases along the South Vietnam border as part of the McNamara Line This line was a combination of infantry units and ground sensors devised to stop PAVN infiltration into South Vietnam across the border and along the Ho Chi Minh Trail When Maj Gen Raymond G Davis took command of the 3rd Marine Division he ordered Marine units to move out of their combat bases and engage the enemy He had noted that the manning of the bases and the defensive posture they developed was contrary to the aggressive style of fighting that Marines favor In early 1969 intelligence reports indicated there had been a large PAVN buildup in the A Shau and Đa Krông Valleys The A Shau was just 10 km east of the Laotian border and some 34 km long while the Đa Krông was several kilometers further east and separated by two mountain ranges The operation named Operation Dawson River South was to comprise 3 distinct phases first was the southern movement of the 9th Marines and supporting units into mutually supporting firebases near the objective area second was a period of intensive patrolling around the firebases and finally the Regiment would attack into the PAVN base areas The Marine operation would be coordinated with supporting actions by the 101st Airborne Division and the Army of the Republic of Vietnam ARVN 2nd Regiment east of the operations area Operation Phase 1 On 18 January the 3rd Battalion 9th Marines was lifted from Vandegrift Combat Base to reoccuppy Firebase Henderson On 20 January Company L 39 Marines reoccuppied Firebase Tun Tavern 16567N 106935E and on the 21st Company A 1st Battalion 9th Marines reoccupied Firebase Shiloh 16515N 106969E On 22 January the 2nd Battalion 9th Marines was lifted from Vandegrift to establish two new firebases further south Dallas 16405N 106967E and Razor 16441N 107002E On 24 January the 9th Marines command post was moved from Vandegrift to Razor On 25 January 39 Marines established Firebase Cunningham 6 km southeast of Razor and over the following four days the 9th Marines command post and five artillery batteries from 2nd Battalion 12th Marines moved to Cunningham UH1Es at Fire Base Cunningham during Operation Dewey Canyon Phase 2 The Operation was renamed Operation Dewey Canyon and on 245 January Companies from 29 and 39 Marines began patrolling south from Razor and Cunningham discovering the PAVN 88th Field Hospital which had been abandoned the previous day On 31 January after a brief firefight with PAVN forces Company G secured Hill 1175 while Company F established Firebase Erskine 16479N 107039E On 1 February Company K established Firebase Lightning which was occupied by the ARVN 1st and 2nd Battalions 2nd Regiment On 2 February Firebase Cunningham was hit by 3040 rounds of PAVN 122mm artillery fire from Laos resulting in 5 Marines killed With bad weather limiting patrolling and resupply the Marine infantry were withdrawn to their bases On 5 February as Company G withdrew from Hill 1175 they were ambushed resulting in 5 Marines killed and 18 wounded while only 2 PAVN bodies were found LCpl Thomas Noonan Jr would be posthumously awarded the Medal of Honor for his actions during the engagement On 10 February Company H 29 Marines captured a large cache of ammunition weapons and equipment while on patrol five kilometers northwest of FSB Cunningham The haul of ammunition included 363 RPG2 rounds and 120 rounds of 60mm mortar ammunition Phase 3 and the raid into Laos The third phase commenced on 11 February 1969 19 Marines engaged a PAVN force preparing to attack Firebase Erskine and killed 25 PAVN Company M repulsed a PAVN platoon killing 18 for the loss of 2 Marines while Company C killed 24 PAVN for the loss of 2 Marines On 16 February Company K 39 Marines killed 17 PAVN On the 17th Company G 29 Marines killed 39 PAVN for the loss of 5 Marines On the early morning of 17 February PAVN sappers attacked Firebase Cunningham resulting in 4 Marines and 37 PAVN killed On 18 February Company A 19 Marines encountered a PAVN bunker system which they overran killing 30 PAVN The following morning Company C continued the attack against nearby PAVN positions killing a further 30 PAVN with total Marine losses of 1 killed On the afternoon of the 20th Company C encountered another PAVN bunker system killing 71 PAVN and capturing 2 122mm field guns Company A continued the attack killing a further 17 PAVN total Marine losses were 6 dead Also on 18 February Company L 39 Marines discovered a PAVN cemetery containing 185 bodies buried in June 1968 As the Marines approached the Laotian border and in response to the artillery attack on Cunningham Major General Davis had sent requests up the chain of command to get permission to enter Laos This led to a redirection of MACVSOGs Operation Prairie Fire to conduct reconnaissance near Base Area 611 in Laos On February 20 Lieutenant General Richard G Stilwell forwarded Davis request to have a limited raid into Base Area 611 up to COMUSMACV General Abrams for his approval By 20 February 29 Marines had both Companies E and H on the Laotian border From their position Company H could see enemy convoys traveling along Route 922 Company H Commanding Officer David F Winecoff later reported The company of course was talking about lets get down on the road and do some ambushing I dont think they really thought that they were going to let us go over into Laos I knew if the military had their way wed be over there in Laos and the company was all up for it With the Paris Peace Talks going on I wasnt sure what route was going to be taken On 21 February Captain Winecoff received a message from Colonel Barrow 9th Marines Commanding Officer to set up an ambush along Route 922 The Captains men needed rest and he requested a postponement but was denied by Colonel Barrow The Captain utilized his 1st and 2nd Platoons and at 1610 1st Platoon moved out and made its way to 2nd Platoons position At 1830 Winecoff briefed his men on the ambush After dark they moved out towards Route 922 about 900 meters away By 0100 Captain Winecoff and Company H were in place and setting up the ambush Within minutes of getting into position they started hearing trucks coming down the road and continued to observe as 40 minutes later a lone truck and one PAVN soldier also walked through the kill zone Winecoff had not wanted the ambush sprung on one truck or soldier realizing that eventually a bigger target would come down the road At 0230 the lights of eight trucks appeared and as three trucks came into the kill zone the column of vehicles stopped Not wanting to give away the ambush or their position Winecoff set off the claymores and the ambush The Marines poured small arms and automatic weapons fire on the three vehicles the forward observer alerted the artillery and rounds bracketed the company position After minutes of fire Captain Winecoff had his men moved forward ensuring that everything was destroyed The company proceeded to move out to the rally point 600 meters away and waited till daylight Later it rejoined with 3rd Platoon who had not been involved with the ambush because of the heavy patrols it had been involved with in the previous days H Company was resupplied and the men rested They had destroyed three trucks and killed eight PAVN soldiers Company H did not suffer any casualties A wounded Marine is helped to an evacuation point After Action Reports of the patrol were met with positive reviews General Abrams formally approved the operation The success of the operation was more valuable than just the destruction of the enemy because it allowed Colonel Barrow to request that continued operations in Laos be approved His reasoning for continued operations was the presence of the enemy in the area was a threat to his troops Barrow noted I put a final comment on my message which said quote Put another way my forces should not be here if ground interdiction of Route 922 not authorized The message finally reached Also on 21 February Company M 39 Marines discovered a PAVN maintenance facility including a bulldozer and on further searching around Hill 1228 discovered 2 122mm field guns and a large tunnel complex inside the mountain On 22 February Company A 19 Marines overran a PAVN position eight kilometers southeast of FSB Erskine killing 7 PAVN for the loss of 1 Marine As Company A continued patrolling they encountered and overran an entrenched PAVN Company killing 105 PAVN for the loss of 11 Marines Captured documents indicated the unit in contact was the 3rd Battalion 9th NVA Regiment also known as the K16 NVA Battalion The Company A commander 1Lt Wesley L Fox would be awarded the Medal of Honor for his actions during the battle Company H was ordered to go down Route 922 on 24 February Morale was low because the Marines were tired after several days of patrolling additionally they did not want to leave the resupplies that included 60 mm mortar ammunition and Crations Company H was to move into Laos followed by Companies E and F and push eastward on the road forcing the PAVN into the 1st and 3rd Battalions After a sixhour night march Company H set up a hasty ambush at 1100 on 24 February six PAVN soldiers walked into their kill zone of which four were killed On February 25 Company H continued to move eastward again engaging PAVN resulting in the capture of one 122 mm field gun two 40mm antiaircraft guns and the killing of eight PAVN soldiers Company H suffered two dead and seven wounded Later William D Morgan was one of the men killed in action when he made a daring dash and directed fire away from Private First Class Robinson Santiago and Private Robert Ballou Robert Ballou was wounded multiple times that day and Robinson Santiago was killedinaction Corporal Morgan was posthumously awarded the Medal of Honor for this action Company H flanked by Companies E and F continued their drive east which was rapid and did not allow for the Companies to conduct thorough searches Advancing much slower would have garnered much more equipment However 2nd Battalion did capture 20 tons of foodstuffs and ammunition while killing 48 PAVN soldiers On 26 February Company F 29 Marines discovered a large cache nine kilometers south of FSB Erskine which included 198 rounds of 122mm artillery ammunition and 1500 rounds of 127mm ammunition for antiaircraft guns On 28 February at 1300 a squad patrol from Company G 29 Marines came under heavy fire from approximately 25 PAVN The squad was pinned down and reinforcements were sent to the location 161817N 1065840E however as the patrol leader had lost his map it was difficult to locate the patrol or use supporting arms After some time patrol was located and an artillery mission was called in which routed PAVN 3 Marines were killed and 12 wounded while PAVN losses were estimated to be 12 dead The three companies were within 1000 meters of the South Vietnamese border by 1 March and were flown by helicopter to Vandegrift Combat Base on 3 March officially ending operations in Laos 2nd Battalion sustained eight killed and 33 wounded during the operation For the record all of the dead were listed as being killed in Quảng Trị Province South Vietnam and for political reasons no reference was made about being in Laos On 27 February Company D discovered a large PAVN weapons cache near Hill 1044 that included 629 rifles and over 100 crewserved weapons With the Marine objectives achieved by early March the operations plan called for the phased withdrawal of the Marines from the operational area however this was hampered by bad weather As 39 Marines withdrew to Firebase Cunningham on 3 March they were ambushed by a PAVN force and PFC Alfred M Wilson would be posthumously awarded the Medal of Honor for his actions during the firefight The operation concluded at 2000 on 18 March as the last Marines arrived back at Vandegrift Outcome and legacy Marine losses were 130 killed and 932 wounded in return the Marines reported 1617 PAVN killed the discovery of 500 tons of arms and munitions and denial of the valley as a PAVN staging area for the duration of the operation Notable decorations and awards during the operation were First Lt Archie Joe Biggers Platoon Leader 9th Regiment US Marine Corps who led the platoon that captured the two 122 mm guns was wounded in action during the operation and was awarded a Silver Star The 9th Marine Regiment and attached units were awarded the Army Presidential Unit Citation In 1971 the operation to clear Highway 9 from Đông Hà Combat Base to the Laotian border was named Operation Dewey Canyon II in an attempt to misdirect enemy attention towards the A Shau Valley instead of Tchepone the actual objective of the combined campaign In April 1971 the Vietnam Veterans Against the War organized a protest rally in Washington DC and named it Operation Dewey
