The number of protesters at Whitegate has risen tonight, despite falling temperatures, with more than 100 taking part in the blockade.
A message went out at tea time for those at the protest in Cork, saying "strength in numbers". Since then, new protesters have been arriving steadily.
There are reports of trucks, lorries and tractors back-to-back all the way into the village of Whitegate, with both a van for chips and coffee in place.
However, the mood is both serious and expectant, more than 13 hours since Mr O'Callaghan said he was sending in the Defence Forces.
Protesters said that this was to the fore of their minds throughout the day.
They also said if the army arrive, there will be no aggression and no violence and that they will stand back and let them do what they have to.
But if there is any sign of the army towing into their trucks, then the protesters said they will tow in first and will reinstate their slow-rolling convoy protest at 5 km/h.
However, protesters said they are hoping that it will not come to that.
Instead, they are hoping that Government will meet one of the four people nominated by protest groups across the country.
They said if Government were to meet them, that the gathering in Whitegate would be over quickly.

Protests also continued today at the fuel depot in Foynes, Co Limerick.
More people began arriving at the protest after 6pm.
Protesters there have facilitated trucks carrying chemicals for the treatment of drinking water to pass the blockade.
Chemifloc trucks have been coming in and out of the depot collecting supplies for Uisce Éireann for the treatment of water.
Foynes is not just a fuel depot, it also stores and distributes chemicals for that very purpose and also has grain and wheat in storage for distribution.
Protesters have agreed to allow two trucks carrying pig feed to leave tomorrow morning.
This evening, the Reidy family, who own the Circle K in Foynes, said they ran out of fuel, running out of diesel at 4.30pm and petrol at 7pm.
They were due to receive a delivery yesterday.
This was to come in the form a truck carrying 36,000 litres of fuel, which was due to leave Whitegate in Cork but that delivery got caught up in the blockade.
Several service stations in Limerick and Clare have run out of fuel.
Protesters at Foynes have reiterated that they are not going to allow any fuel trucks to leave the depot.

The blockade at Galway Harbour is continuing this evening, where protesters remain defiant, with hundreds of additional people now taking part.
The impact of the blockage of depots across the country is beginning to impact supplies at forecourts in the west.
There is no diesel in Acaill, Co Mayo, or Béal an Mhuirthead, with queues in Iorras seen queueing for fuel, as well as Salthill, Athenry and Casla reporting low levels of fuel.
Turloughmore is also affected.
A tanker is reportedly off the coast of Kerry, coming from Antwerp and is expected to dock at Galway Harbour at 8am tomorrow with 6 million litres of fuel.
However, the tanker will remain on the bay and will not be able to pass the blockade, according to the protesters.
There will be significant costs incurred for every hour at sea without delivering the fuel.
The tanker on Galway Bay will be a visceral reminder of the impact of the fuel blockades across the country. It will no doubt lead to calls for an immediate de-escalation of the growing crisis.
Protesters have said there will be no oil coming in or out of Galway.
Tanks at the depot are full as a result.
